Educate Me On Wheels

[Malarkey21]

can anyone think of any other drawbacks of a slight wider stance?

its a bit of a mix between positive and negative and you really can tell without driving, but on paper.. Wider track with will be more stable both on and off road. it will change the motion ratio of the wheel, so dampers could have a different feel either good or bad. Change in scrub radius (depending how much wider your tire sticks out), there is a lot of info about this out there but my guess is you could notice tire wear the most. The software tuning for the EPS, Stability control, Traction control, and ABS will be a bit effected too. Example, since my 35 are heavier then stock wheels, the brake pressure for the stability control to grab the wheel is not enough so the well continues to turn but it does make it more fun for sliding around in the snow.

I also want to say, I've never tuned EPS, Stability control, Traction control, or ABS, so I dont know how much it will be effected (Might not even be able to notice) but most calibrations are very specific to trim levels and wheel / tire / engine combinations in my experience.

lots of fun stuff with vehicle dynamics haha. easy to change a bunch of things since a lot of them work together.

I'm looking at the same thing, it seems like every few years I'm relearning this stuff because it's kinda one and done. LOL

This link is cool. You put in your current setup and it figures out the rest, but also has a graph on the right to show you location of the tire in the wheel well, as well as gives you an idea of distances to vitals around you.

You can also play with offset numbers to get your wheel location dialed to your liking.


IE: I want the new wheel to be at the same location (inner area closest to suspension) as possible.
So, all things equal, moving to 37"x12.5 about 25mm offset is good. Then adjust for increase of wheel width.

There is also a simple chart at the bottom of the page.
Stock JTR wheel = 7.5w and +44.45 offset.

To keep a stock-ish inner relationship to the suspension;
-An 8w wheel would be +38mm
-An 8.5w wheel would be +32mm
