Tire Diameter ? everyone plz chime in

[Smokaholik]

Ok guys i have researched and researched and still have not come up with a valid answer. heres the deal i have 265/35/18 tires on the front and i wanna run 285/40/18 tires on the back.(found a good deal i can afford) So question is will i run into any abs problems running these different diameter tires? Any and all input would be so much appreciated being my rear tires are about to die anytime now. so has anyone ran this combo & is it a valid combo for a antifree abs problem. Everyone/anyone plz chime in and school me on some knowledge PLZ. THX

265/35/18s have a diameter of 25.3" which may vary by brand


285/40/18s have a diameter of 27.1" which may vary by brand also.

You will have ABS issues with those diameters though.

I looked up a 285/35/18 and it had a diameter of 25.9", match that with a 265/35/18 and you would be good. Basically to find out, put in the tire size you are looking for at tirerack, and then look at the specs of the tire, it will tell you the diameter. Find tires that are within .5 diameter of one another and you should not have ABS issues.
