Just wanted some help on what the best tyre size is for 18" wheels on a coop.

In order to keep the diameter of the wheel/tyre the same as the standard 205/50/16 (612mm), you could go for 215/35/18 (607mm) or 225/35/18 (615mm). Anything else will mean that your speedo will read outside of allowable tolerances (not sure if this is a legal requirement <img src="/forum/images/graemlins/confused.gif" alt="" />, but any good tyre place would advise you of this).

I can't advise whether these will actually fit within the wheel arch, but I'm sure someone else will be able to <img src="/forum/images/graemlins/wink.gif" alt="" />.

i got 225/35 18 ... fit's nice..

cheers

coen

i also have 225/35/18,and fits perfect.
even 235/35/18 would fit nice......

I know that Barbz runs 225 35 18,I was going for 215`s but he feels 225`s are the best bet

225x35x18 fits. 225x40x18 won't fit ! Will rub on the inner side (on my car at least)

Thanks for that looks like its 225/35/18 then.

@ jax

what kind of rims do you have in your pic...?

any chance of a large pic....? <img src="/forum/images/graemlins/smile.gif" alt="" />

thanks

Will 215/40/18 fit? Or will they catch?

i am 99% sure 225 40 18 will fit without touching, especially toyo T1S

If the Toyos do fit it will be because they are smaller in diameter than most 225/40s.

But the correct size still is 225/35-18

...really do hope so since I`ve thought about get a set of 18" this summer! <img src="/forum/images/graemlins/smile.gif" alt="" />

just likew buying a pair of jeans, one 32 waist will fit another will be as snug as a bug in a rug! personally i have about 10mm clearance all round my 225 35 toyo tyres
