Do larger wheels effect Cruise Control?
Hey guys,
I just put 18" wheels on my 1993 400E and the stock size is 15". As soon as I put them on I notice my cruise control doesn't work above 40 MPH and if i try to set it I can feel a little jolt and then it just quits. Any link here? Or is it just a coincidence and my cruise is going out? Thanks!

If they're all the same size (exactly), should be fine. Are they staggered?

I had issues when I ran staggered wheels on my 1996 E320. Went back to stock and they went away.

They aren't staggered all 4 of them are 9.5" wide. The tread size is different though I have a 25% aspect ration on the front and 45% on the back...I'm switching to 35s though cause the 45s rub.

Im going to use the calculator and see if 35s on the rear will solve the problem

Actually I gave false info. The fronts and backs are 40% aspect but the fronts are 225 and the rears are 255

There ya go, different rolling circumference = no cruise control.

What would you suggest for an all around tire size? I'm thinking 225/40Z/R18s on all 4 would be the best.

I would think that would be a bit rough and depending on where you live would increase the likely hood of a damaged wheel/tire due to a pot hole or the like. I run 17" on the 190 with 215/45 all around. Excellent performance and the tires look decent on the car. I ran 40's for a bit and they were too thin IMO.

These wheels are pretty good quality. I would go with 17s but I already bought the 18s and I am having trouble trying to sell them.
