On a tight budget. Need new tires and rims. Going from stock 15" steelies to 17" rims, and need new 17" allseason/summer performance tires. Both simply need to be "average", not looking for anything really nice, but i need reliability with both. Max I can spend is $800 on all, that's $100 a wheel, and $100 a rim. Looking for 5-6 spoke wheels, doesn't matter really if they are chrom/silver or black. Also, going from 15" to 17", anything I need to know? I know about tire conversion and all that, but nothing else has to be done? Going from 205-60-15 TO 215-50-17, i THINK. There is a 2MPH difference if i did the math right, that OK or a no go?
