soooo i found some rims i want and that got my lookin into tires to match and i had some question as to sizing and stuff...i'm lookin at some nitto 555's for the front (265/35r20) and 555r's for the rear (305/35r20) and i was wondering if the diameter variance from the stock tires to the new ones was a problem to look at...i was also thinkin about some hankook ventus evos all around (fronts 255/30r20 rear 305/25r20) but those are smaller than the stock rims/tires...so how bad can you get in terms of diameter variance and what are the negative side effects?

 

A 25 series tire? Might as well get wagon wheels. Stick with your first set you mentioned.

 

will there be any problem with the rear being about 4% bigger?

 

Having a taller tire in the rear will effect the speedo a bit.
