Hi, anyone had any experiance with these tyres, not worried what they are like 'on road' cuz my cherokee dont touch the tarmac, off road use only.

Your comments please, negative or positive.

Thanks

Very Popular Simex tread copy, a little cheaper too.

What size are you looking at? Insa Turbo Special tracks are cheaper and now do a 285/75 (33") in the same Simex tread pattern.

TSl Super Swamper Boggers are becoming more popular, If your road mileage is low. The Bogger pattern seems to be better a better all rounder.

from what I have been led to beleive from a guy who recently lost his insurance claim for not haveing road legal tyres, TSL Swampers boggers are not uk legal for road use, NO 'e' mark and hence illegal to use, invalidating your insurance, and hence Vosa love to see them.

The penalties for having illegal tyres are currently up to a £2500 fine and 3 penalty points PER TYRE!

I know what my choice would be.....

They're also as heavy as hell, much heavier than a similar Simex, about 25kg/tyre. Your axles will love you for it! #-o

But, they do the business in the mud. No problems there!

yes - perform well for a jelly mold!!!!

OK thanks for the feedback.

So what do you guys think are best, no onroad use at all, trailered vehicle so extreme offroad use only.

Im thinking the shortlist will be simex or boggers, so feeback on these tyres would be appreciated, or are there others in the mix?

I would like 35s but will probably settle for 33s

description of vehicle is in signiture

Look forward to comments

Both fantastic tyres, Boggers better in mud, Simex better on sideslopes. Or option 3, Interco Super Swampers. They're a fantastic allrounder. Just stuck a set of 38s on a YJ with awsome results 8-)

Are you gonna re-gear for the 33's or 35's?

Tragic were did you get the 38s from and what size are they.cleggy

Jeepers XJ · « **Reply #9 on:** April 26, 2009, 12:18:15 AM »

Warthog - No plans to change gearing to start with, only used in low box so not sure if it will be an issue or not.

The thinking is i may get away with it with 33s, 35s will probably be pushing it.

Will probably give it a go and when i break it i will upgrade it thats how it works isnt it?

Good advice but not a problem for a trailored vehicle.

I have a 4.0L TJ with stock gearing and 265/75/16 Insa Turbo simex copies on whitch is just about 32" and it gets by offroad in low box. Downhill can be a problem though with a lack of engine breaking for control. Any larger tyres and any severe downhill decents would require Automatic style cadance breaking for extra control etc. It also struggles gearing wise on rocky slopes. The wheel speed is too high for the terrain and gearing so you are reliant on the clutch much much more to get the nose up obsticles etc. Bad point there is clutch wear and tear plus again control. Also tyre size is a mindfield. Most all tyres are not the actual size they say. Most 33's are true size 31.5"-32", 31's are 28"-29.5" and so on depending on manufacturer and believe me an ich does make a big differacne to the gearing. Also be warned some tyres are oversize, some retreads because of the carcasses they use can be an inch and a half bigger than the size stated also. which on a truck like a cherry is the differance between a snugg fitt and having to take an angle grinder to all the arches. Another thing is I also have a set of 33/14/15 boggers and they slightly bigger (ok much wider, before warthog jumps in!!!) than the Insa turbos but actually much lighter but I dont know what size tyre Tragic was using.

I have got to the point personaly where gearing is an issue but the only way you will really know is by sucking it an seeing.

Another thing to remember is the bigger you go tyre wise the more important your brake setup will become to you. 35's on standard breaks and if your still got drum brakes on the rear (we all know the drums are useless after getting wet and muddy ) will give you some hairy moments from what I have read and heard.

=D>
I'm currently running 35s (which actually measure 33.5") on 4.56s. Seems to be pretty much spot on gearingwise.
The YJ on 38s (from Patrick at Specialist Leisure, he was cheaper than Simon at Devon 4X4) is running 4.88 in D60s front and rear, and also seems to be a good combination.

X2 on the brakes too. I wouldn't want to go bigger than 33" on the stock brakes, I have the SSBC rear discs on mine with the 35s and its stops reasonably well. I haven't hit anything yet anyway.....
If it's a trailor queen you should be OK, just dont go above 40!

hang on bogger not legal what do la super trux say bout that

also clasics and old militarys run on tyres that have to come from out side the poxy wanky eu so no e mark

you cant tell me that maybe as many 20.000 odball /clasics and other cant legaly be on the road

i mean if this was true your mot station would be liable if an mot was gained on these tyres and then the insurance was void

Panic mechanic! · « **Reply #13 on:** April 26, 2009, 10:34:07 AM »

selling you a tyre that is not street legal is not illegal, its your tyre and your responsibility, it all comes down to construction and use regs again,vintage cars can get away with it cos their was no 'e' mark when they were produced but plod only knows about newer vehicles,MOT stations aren't liable cos they use the old, it wasn't on there when it was mot'd, after all the mot is only valid on the day the vehicle is examined.etc etc
they are approved by the DOT in the US for street use but not over here.
this guy with the landie only lost out on his claim due to the fact that insurance companies are now checking up on home modified off roaders thanks to that guy who killed his kids in the river,just as another point of reference if they look at a lift kit and find its not 'e' marked it could be deemed illegal cos its not been stress tested etc over here,its why everything on a modern day vehicle has to carry to carry one.
its also why in france / germany if your vehicle is not 'e' marked on lights etc, it will fail its annual inpsection

Bubba · « **Reply #14 on:** April 26, 2009, 10:49:20 AM »

no you miss my point panic apart from hgv tests i have never seen at mot the tyres checked for e mark only condtition and correct fitting also old clasics have to buy new tyres therfore the tyres have to be emarked

basicaly you are telling us
that acording to construction and use that is forever getting qouted these days
all our moters are not legal and our insurers are breaking the law by offering cover so we should all be in jail

Panic mechanic! · « **Reply #15 on:** April 26, 2009, 11:11:58 AM »

they don't need to check your tyres, cos your tyres are your responsibility, not theirs, I have never seem a mot station look for it either.I have seen an MOT station tho spot a tyre that no one else had previously being a narrower profile altho identicle otherwise, which surprised the owner.
Insurers aren't breaking the law, cos if you haven't told them that your tyres aren't approved for UK use, you have voided the policy,not them, its your responsibilty to tell them of any thing that is different from standard spec, thats why you get that statement on your insurance about modifying your vehicle to tell them etc.
The time the problem picks up is when someone has a serious/fatal accident , the vehicle then gets dragged in and inspected by the insuance/ police,thats when the shit hits the fan.
the only time things like this normally get picked up is when your vehicle is requested for a VIC check after being repaired and it has to go to a ministry test station.

Bubba · « **Reply #16 on:** April 26, 2009, 12:59:52 PM »

as i say we give our unsurers a full breakdown of our motors down listing the brands of parts therfore they know everything
and would bereaking the law to knowingly provide a service [cover]they would be obliged to i am sorry but your badass sway bar is not an approved disign or manufacturer therfore we canot lawfully cover you as we would liable

You'll notice a differance in how the Truck performs in low box too. It may pay ya to search a few posts on here referance; Gearing

From how i see Asylums truck perform with 285/65R16 Special Track (just shy of 32") I think that this tyre size is the best compromise for the Gearing on stock UK XJ's and TJ's His traction off-road is good, but low end control is a awkward.

Your wheel bearings wont last too long either with 33's -35's meats. But i think you'll have to live with that, unless you upgrade to Warn hubs or similiar.

Getting a set of 16" Rims can also open up the options for cheaper tyre choice/more tread patterns. As the patterns generally get made for 16" rims first.

Hope that helps?

A Jeep Grown up will hopefully come along now and agree/disagree and correct me for what i have written :lol:

Jeepers XJ · « **Reply #19 on:** April 26, 2009, 11:06:44 PM »

Warthog - Great advice all the way.

Spot on with the warn hubs as the original have non replaceable bearings im sure warn ones will be a deffo.

Will take a look at some old posts regarding gearing

thanks again.

From what I've read most people don't reckon it's worth re-gearing a D35c axle if your planning on running 35" tyre, they all point to upgrading the axle to min D44/8.8. It seems the whole axle design is not capable of running more than 32/33" and that's with a v. light right foot. This view is mainly from the US so may be more relevant for rock crawling rather than mud but might be worth bearing in mind.

I run 32" tyres off-road on a std 3.73 ratio and there are times when I would like a little more control. :-(
