bought new rims!

[b0b]

well, i ordered some 18" RS limited rims off of ebay. they are gunmetal with a silver lip. i am interested to see how they look on the lapis blue. they are 18x7.5" with a 42 offset.

what size tires should i go for to minimize rubbing, and keep my spedometer accurate?

thank you.

if ur car is lowered, and u will roll the fender go with 225/40/18
if u dont want to roll the fender then 215/40/18

I think you are going to have to roll the fenders reguardless. I have 18x7.5 ADR's with +48 offset and 225/40/18, and I rub when taking hard turns with people in the back.

i guess ill go with 215/40/18's then

The 225/40 series tires is the reason why you are rubbing even with a +48 offset. A +42 offset with 215 series tires will be at least 4mm farther from the outer edge of the wheel well than a +48 offset with 225 series tires. This is based according to the math that 215 is 10mm less in width than 225, but a +48 offset sticks out 6mm less than than +42 (10mm - 6mm = 4mm). Why 4mm or 0.16 inches should make such a big difference I have no freaking clue but apparently it makes all the difference in the world to the wheel parameters of a Mazda6; +42 or +45 offset but 215/40 shouldn't rub given 000000 and ATL as proof.

I guess what also makes the difference is that 215/40/18's provide 0.3" or 7.62mm less overall wheel+tire diameter than 225/40/18, keeping it that much further away from scraping even in load bearing situations...
