i'm thinking about getting ssr gt3 wheels for my car--19x8.5 in front and 19x10 in back. i've been trying to look for good tires for the wheels, but i'm not too familiar with tire size selection. and many tires don't allow for the 10" rim width for the rears. the brand i can find thats reasonable in price are toyo t1-s wheels. using tire size calculators, i've been trying to find right size tires to match the stock wheel sizes. can anyone tell me what is recommended in selecting tire sizes? does the difference in section width between front and back tires matter? does the aspect ratio have to be the same for front and back tires?

 

The biggest considerations are wheel offset when changing to new wheel/tires. Make sure tohe tire you select will fit the rim width, and you need to consider overall diameter/circumference that comes reasonably close to your stock set. If you can find a spec for Revs per mile, it's even more accurate as different manufacture's sizes may vary within the stated size.
