Staggered tire setup
I need to purchase a new set of rear tires for a 11" x 22" rim. The front wheels are 9.5" x 22" wrapped in 285/35-22 Toyo Proxy ST tires. I previously had 315/30-22 Toyo's on the rear. Unfortunately this model of tire is now discontinued. And this particular size seems to be very rare, and very expensive. - Will a 285/35-22 tire fit a 11"x 22" rim? Some sources say this tire fits a 9.5-10.5" rim some say 9.5-11. - Due to the discontinued tire issue, I will be using a different tire model on the rear. If it turns out this is a very bad idea, then I will not be mounting these rims at all. I don't want to pay for 4 new tires. I understand different brands might differ in overall diameters, this data may be difficult to find. - The front tires have more than 80% tread left. Here are some calculations between the stock tire, 285, and 315: from this calculator http://www.1010tires.com/tiresizecal...?action=submit Stock - 235/65 R17 : Overall diam- 29.02, Revs/mile- 716.7 Current front 285/35 R22: Overall diam- 29.85, Revs/mile- 696.8 Old rear 315/30 R22: Overall diam- 29.44, Revs/mile- 406.5 I am not clear on the tolerance numbers. Am I looking for 1-2% max tolerance between front and rear diameters? Revs per mile? Stock wheel diameter and rev diameter compared to after market wheels etc. I guess, I really want to know if I can fit a 285/35 tire on the 11" rim. This will probably be my best shot at matching the fronts without buying new front tires. If not what are my other options for tire sizes for this rim and front tire combo? Thank you for any guidance,

On that site (1010tires.com) it will tell you when your choice of tire size will create problems. It is usually when the difference is greater/lesser than 3%.
If you enter (staggered) tire sizes and they work together (as well as fit the rim sizes listed)...you won't get any warning. But if they don't work and the difference goes over 3% (+/-) then you will get a warning stating that there may be an issue.

There are a a few 285/35/22 tires that have an 11" range.
This one comes to mind: Pirelli*Scorpion Zero Asimmetrico Comes in at 29.8" overall diameter, and the ability to mount on an 11" rim. I;m sure you could find others that will mount on a 11" rim safely as well!
