Can I put slightly larger diameter tire?
Hello,
My car originally needs 225/70R16. A friend could give me a set of alloy rims with 225/75R16. This is 3.12% diameter increase. I read 'stay within 3%'. Can I take these 225/75R16 or should I avoid them? Main concern - can this much of an increase do any harm to transmission?? I know about the speed / odometer reading, that's not an issue really. The real issue is transmission. Maybe there are other serious concerns in this given case? Please suggest if you are knowledgeable. Thank you.

Just google it. The 75 series tire will be higher than the original 70 series. Actually 75 % of 225mm width will be the total height, although only half that affects ride height.
Only real risk would be rubbing of a front tire on the wheel well or possibly other suspension part. Only real way to know for sure is to put on one of the front tires and cycle it lock to lock and make sure there is clearance without rubbing. Probably will be ok.
Free advice worth everything you pay for it.
