Ok so I'll more than likely sound like a complete muppet for asking but, will it be ok using a 225 75 15  on one side and a 215 75 15 on the other for a few weeks? as I want to get the XJ on the road and the part worn place by me only has 225's in

and the other daft tyre related question is   whats the biggest tyre that will fit without a lift kit ?

[gazjeep]

Biggest without lift kit to stop issues would be 235.

Any bigger & you can have rubbing issues, its also the biggest tyre that will fit as a full sized spare on the standard bracket in the boot with the back seat upright.

As for mixing tyre sizes, personnally I wouldnt, all tyres need to be the same to avoid potential drivetrain imbalancing issues 

[andy-macg]

cheers  mate, looks like I'll have to bite the bullet and get my new tyres sooner but at least I now now that I,can go up to 235's


thinking of getting  a set of   either

Andy,

If its of any use I have got a set of wheels and tyres in my Garage in Bromsgrove, so not far away if it gets you out of a hole for a few weeks etc.

Ready to put straight on.

[Nosebolt]

if they are the same make and wear there will be a 14mm (0.6") difference in diameter if different makes or wear there could be over an inch difference, so the short answer as above is NO

[andy-macg]

cheers for the offer Jay

but  fate has just been very very kind to me, but a chap up the road whos in to suzuki sj's  has just offered me a pair of 225 70 15  grabber at2's  that have been hardly used  so  shall be taking them off his hands till I,can aford my 235's

[chrisjones]

You're still going to need a set of 4 the same size though.

If you had freewheel hubs you could probably get away with having a slightly different size front to back, but I'd not risk it on an XJ.

Jay's offer sounds like a good one to me.

[jay140285]

You looking at running 225 70 15 and then 225 75 15 so still 2 varying sizes.

[andy-macg]

the XJ is on 215/75/15s at present but 1 is fubar ,but none of the part worn places by me have none,

out of curiosity jay  what size are the wheels and tyres ?

[Nosebolt]

just to make it clear, if ALL 4 tyres are not the same size you risk damaging your transfer box and that will cost more than a set of new tyres

[bgbazz]

 






with you NB and Gaz and everyone else trying to advise.

[Bubba]

yup

[jay140285]

I have a set of 31X10.5 15 on XJ alloys. Biggest you can go!

[andy-macg]

cheers guys   see I never knew that  as I'm used to clonky old series landys  

tis a good job I hadnt actually told the chap id have his 225's  in that case.


Jay   did they rub at all  ??

[jay140285]

Not in day to day driving, rubbed very very slightly when off roading but nothing to worry about.

[andy-macg]

sounds very interesting     Jay

[jay140285]

PM's sent!

[andy-macg]

[jay140285]

And accepted.

Back to the origional post.
You CANT have different sized tyres on the same axle.

[isle of man]

Tyres are a world of pain!!!

The more you want the more it will cost you.

[ShayneJ]

Late to the party but just to reiterate DON'T mix tire sizes.
And even different brands can have significant difference
In rolling radius even if marked up the same.
Please stick to same make same size or your drive train
Will chuck its toys out in a loud and expencive way!

You have been warned.      Again

[jay140285]

He has 4 of the same now folks, all sorted.

[Dave69]

if you want the front two tyres different to the back two tyres then remove the front prop shaft
