Not suggested. If you put on a 245/45-18 tire instead of the stock 245/40-18, the car will travel 3.7% faster than what is displayed on the speedo. Most tire shops won't mount a set up that changes the speedo more than 2%.

I did mount mine at Discount Tire today..170 bucks for mounting, spin balancing, tpms rebuild....yuck...replace the 245/40/18 with 245/45/18...In deed, they seem to move faster :) The guy at the shop said that I shouldn't have any problem with the tires except I might experience premature/abnormal wear ...hmm..any body see any negative side effects of using these tires?
Thanks
