    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Looking to pull the trigger on some 22 x 9" wheels and slightly wider tires (265 series) for summer.

To maintain close to the same diameter as stock 21" tires, I would need to go with 265/35/22, and that would result in +1% larger diameter but the sidewall would be smaller by .3", and in turn, firmer ride. Not sure I want to sacrifice that much ride quality. Therefore, was thinking of going with a larger tire, 265/40/22, of which there are many more options available, but the diameter difference is +4.5% (outside the recommended max of 3%), but the sidewall is .2" greater than the stock 21" tires, thus hopefully helping with ride quality. Other bonus is that there is slightly less chance of a damaged wheel due to poor roads. Supplier confirms this will fit, so not seeking advice on aesthetics, ride or fitment.

Question is this to those knowledgeable with vehicle mechanics - other than the speedometer showing a slower speed than actual, is there any risk to mechanical systems on the car if I have 4 larger diameter tires (ie. the 265/40/22), but all the same size on all 4 corners?

Thanks in advance.
 
The 3% rule is for staggered setups (front vs back diameter) although I would never go above 1-2% for a staggered setup. 4.5% is still a pretty large diameter increase for all four wheels and will definitely change how the vehicle sits and looks. It shouldn't have any detrimental mechanical side effects other than possibly faster wear on the brakes because of the increased weight and inertia.

I would also make sure there are no clearance or rubbing issues with the larger tires.

So these should work… depending on true fender clearances. Thoughts?
