So I kind of got the basics of wheel sizes figured out, but how do you know which tire fits on your rim? I’m looking at getting 18x8 ET35 front wheels and 18x9 ET35 rear wheels.

Et is offset which moves wheel in/out. The gap u refer to is the clearance between tire circumference and fender lip which is increased with lower profile tires which is why u have coil overs to adjust ride height. If coil overs are available it probably means there is a website that caters to your …

[image] TheMidnightNarwhal: recommended tire size for the rim and it should be good to go Wrong, wrong, wrong! You’ve changed the wheel size based on forum info and you just want a tire that fits the rim and assume it will fit. NO. Tires are spec’ed out to fit a range of rim widths and there …

Sorry I think you misunderstood. In that certain tire range for the rim, there will be a optimal sizes, that’s what I meant. And I know my rear tires will be not the same size as the front.

With the greatest respect, I’m worried that you’re attempting to do something that if done without the proper knowledge will result in a safety failure.

That information will be located on a vehicle tire placard which is usually on a doorpost or in the glove box - but occasionally will be found on the fuel filler door or on the trunk lid. From that you need to …

Sorry I got sidetracked on wheels. Tire Rack shows these 18" for the ‘performance pack’ option, so they’ll fit: 225/40x18 front/255/35x18 rear. The rears are listed as suitable for 8.5"-10" rim widths. Is this the info you need? If not, why not?

Bolt pattern is good. The wheels mount, another guys will have the same wheels as mine.

Bolt pattern and offset checks out.

What do you consider as a tire shop? I’m in Quebec Canada so all I know nearby is Costco and Canadian Tire.
