I'm trying, believe me. Going on vacation next week. Going to Colorado Springs, then to Moab, then to Lake Powell Ut, then to Denver, then to Cheyenne Wy, then to Black Hills SD, then home on the 19th. Unless I get a bug up my a$$ and say screw it with work and e-mail them my retirement request. Doing a trackday at Pitt Race on 7/25 for sure. :driving: Trying to work my schedule so that I can get more time for Z things. :driving:


Maybe ill just have to go to the track to see it lol that track is only like 20 min from my house.

Original wheels were 11" +10 offset. You widened them by 1.5" or 38.1mm. Now take that 38.1mm and divide it by 2 to get 19.05. You then add 19.05 to your +10 offset giving you a final offset of +29.

Hope that helps.

normally youd be right but in this case since the entire 1.5 inches was added to the back you do not divide anything by half because the whole additionaly 38.1mm was added all on the backside none on the front, and its only 45 not 48 because you lose 1/16th of an inch when they make the seperation cut

Nope. I'm 100% correct. I've widened wheels before. You're correct about the 1/16th part (or 1.5mm). So actually his offset is closer to +30 than +29.

1010TIRES.COM - Wheel Offset Calculator

Plug in 11 wide and +10 offset on the top
Plug in 12.5 wide and +29 on the bottom

Then try it with your numbers.

Let me know what you figured out.

;)

Being right hurts...

This kind of stuff drives me nuts. The OP listed offsets that were completely wrong because they didn't know how to calculate the final offsets once the wheels were widened. Now people reading through this thread will come across that post and order wheels in that exact offset. When they get them and put them on, they will realize that the thousands of dollars they spent on their wheels went down the drain. Not cool in my opinion.

What the mods should do is go and edit his post for future members.

Bottom line is that if you don't know what your talking about or don't understand offsets, please don't post.

Wanting to keep my original 40th rims, I also went to 265/35/19 Front and 305/30/19 Rear. Hankook EVO2's for me.

Tire fitment question?

Wheel width range for a 285/30/20 is 9.5" - 10.5"

Am I going to run into any problems putting a 285/30/20 on an 11" wide rim? If so, what concerns will there be?

I need all season tires and 285/30/20 is as big of an All Season Tire that I can find.

Thanks

Ok so I did go back and edit my posts to show the corrected offset, and it's not like I'm a retard drooling on myself, I made a simple oversight when figuring the end result but obviously I do know a little because my physical measurements are spot on or else I would've been the guy whose money went down the drain, so please, next time try just saying "Hey, could you go back and edit your posts so there's no confusion for future members ordering wheel sizes" instead of attacking my character and intelligence.
thanks, from a diplomatic pacifist car enthusiast.
