Title: Another tyre question
Post by: charger on April 18, 2009, 01:31:28 PM
I have 235/65/17 stock set up now  Just got a 2" lift & getting some 16" rims off Ivan. When I get new AT's what would be the best tyre size was thinking 245/75/16 would this be ok?

There is a Tyre Calculator button on this site which might help you decide: http://www.tyretraders.co.uk (http://www.tyretraders.co.uk" onclick="window.open(this.href);return false;)

I find this one much better,actually shows the comparison and also the differences in measurements both side on and end on.Only drawback is that it only does metric sizes not imperial

normally when changing tyres/wheel size, if you go up a inch on the wheel diameter, you go down a  ratio on the tyre profile,eg: changing from a 205/75/16  to a 17 inch wheel, you would want a 215/65/17 tyre

so since you are changing from a 235/65/17 you should have no prob with the 245/75/16 as long as the rim width is wide enough. but just as easy to get 235/75/16's your overall tyre diameter should be ok

When you tried the wheels, they were fitted with 245/70r16 tyres., so you know that size fits.

I presume the next size up would be 245/75r16.

Hopefully, I should be getting the rims back today after getting the tyres removed.  Will pm you when I do.
