Hey guys I bought my Z with these wheels, and now the tires are getting low, I was wondering if there are ways to tell the width of the wheel without taking the tires off.

I have 19" Enkei Racing RP03's.

Thanks!

 

Take the wheel off and look for the size listed on the back of the wheel. http://www.enkei.com/size_chart/rp03.pdf also gives you the available sizes

 

a. If you can get under the car see if you can find the size on the back of the wheel.

b. Measure wheel with with a ruler. Not accurate but close enough.

 

Put a mirror behind the wheel. Shine a light on the back of the spokes - find the spot with the mirror and see what the stamp says. Or jack the car up and take one off; or bring it to a garage / wheel shop and ask them to do some free inspection like brakes, and take a peek.

 

Great, I'll take one off and look behind it.

I'm thinking about running 255/35/19 front and 285/35/19 rear, is that okay? Does the wheel width affect tire sizing?

Thanks guys!

 

Yes. Wider the wheel - wider the tire. I can give you no recommendations unless I know the wheel size.

 

Ugh I checked the fronts and they are 19x8.5, still have to check the back :P

 

And the rear wheels is???
