tire size what was the largest

what is the largest tire u can fit under a bone stock blazer

[79Shortbox]

I have heard that it's 33s. I fit 31s on my stock 2wd. You should be able to fit 33s pretty easy with no problems.

depends on how bad your springs are worn out. ive had a blazer with 33s that didnt rub and ive seen a blazer with 32s that rubbed on turns

Lot of it depends on width of tire.  33x10..50 will fit easier than 33x12.50.  Same also goes for backspacing and wheel width.

Alot of companies are no longer manufacturing 33's. A 285/75/R15 or R16 is the same hieght just slightly narrower. A 305/70 is exactly the same as a 33/12.50 only about an eight of an inch shorter. More than likely your best bet would be to go with a 31X10.50 or a 32X11.50 but watch the width of your rim. They look tacky on a factory 6in wheel. Try to stick with 8in widths or wider but I wouldn't go more than 10in wheels. 12's or 15's would rub the inside of the fenders. I have an 82 K20 pick-up with 33s and had to cut the inside corner of the fender. The andvantage with a Blazer is there won't be as much weight on the front wheels. Stay away from Mickey Thompson Baja Claws! They sell them in radials now but still aren't worth the money. They only last about 13 months.

If you want 33"s to fit nicely just throw in an add a leaf and a spacer in the rear. A set of 2" spacers on the rear hubs make the stance a lot nicer looking and widens your track 4"
