Wheel Offset and Tire Size Calculator

[Anonymous]

like the wheel and tire size calculator. how do you determine the widest tire size based on wheel dimensions?

ex. what is the widest tire you can fit on an 18 x 7.5, +45 offset wheel?

i found a set of gram lights and caleb(o4coupe) said he fit them on his car one day but i would like yalls opinion. The guy who has them says they are a +20 offset is that right, and would they work?

They wouldn't.  Just because they are Gram Lights doesn't mean they will fit.  You need to make sure that they are the correct size.  A +20 offset will not fit our cars unless it's like a 4" wide wheel.  Please read the OP of this thread.  It's intended purpose was to help you understand how to figure out what wheels will fit.  You obviously didn't read the OP if you're asking questions like that.  I know it's a lot of information, but it's GOOD information if you don't understand wheel and tire sizes.

rims-n-tires website has a really good calculator not only for offset  but also for tires

gives a visual feel for the difference between rims

This is a pretty good tool to use too.

Im thinking of going with a new set of shoez

7.5
5X114.3
42mm offset
on 225/40/18 tires

I'm pretty sure i'll be ok but any thoughts are well appreciated! What is the typical range of offset we can run without any problems... 38-45?

...I can't remember what my offset is now that I am running...

Those offsets will be fine

[timot_one]

Offset is dependent on the width of the wheel Billy.  The wheels will be fine because that is the same size as my summer wheel set up.  The tires are a bit skinny for my taste, but you should be fine with 225's.  I have 245's on my wheels right now.

Kool, I bought the rims this morning lolz, couldn't pass up on the price. Maybe I will run 235 tires... we will see!

If you have the opportunity, run 235's.  If you want to be a baller like me, run 245's.
