Just been looking for potential tires but I really want to keep my stock steelies, cause they are SO 1979!! How wide can I go on the stock rims? Is there some kind of ratio for rim to tire width? Would something that's a 10.5 fit? how bout 12.5? Anyone know? Thanks!! :confused:

I got 10.5 on stock tracker wheels with no probs.I would do 12.5 too.But that is just me,if they come off the rim when you are out somewhere they are easier to get back on.

they will wear funny in the middle. you will end up runnign a lower pressure to get it to run flat across teh tread surface. lower ppressures increase the wear rates.

stockers are only a 6 or 7" arent they, so wouldnt a 10.50 be fine????

i know guys runing 12.50 on stocker rims but i wouldn't recomend it like sj-x 500 says, they will wear out in the middle. 10.50 should be okay, i got a 10.50 wide tire on a stock toy rim in my garage and it fits fine

8'' for 10.50's
10 for 12.50's

i've seen a 14 wide bogger on a 7.5 rim....


i dont think that there's a right or wrong answer to this "problem"

if you like the rim's... put tires on em.

I like to err on the skinny side for wheeling, and the wide side for looks. I have ran 13.5 wide on 8's with no issues, ran them on 10's too. My way of thinking is 12.50 wide on 8's, and anything over get's 10's.

I like the skinnier rim over to wide a rim !

Skinnier rims tend to keep the tires on better when aired down ----but dont go too excessively skinny to width of tire !

An 8 inch rim with a 12.5 works well !

10.5 is max i would go on a stock rim. i got 13.5 on a 8inch rim. wears good. and never blown a bead..... even at 6psi. ask big ern how wide his rims are and how many bleads he blows hahaha

his blew becuase he didnt alow then to seat before he wheeled....



nothing to do with width......


plus he was wheeling.... not climbing stump's at stave.

last time i talked to him he was running a 12.5 inch tire on a 10 inch rim ... doesnt take a rocket scientist to figure out why he blew so many beeds before the bead locks


he may not have been climbing stumps.... but he also wasnt doing donuts

if that was a shot at aaron.
i bet some people would argue that.

if it was a shot at me..

try harder.

right... 12.5 on a 10...

BUT

he put them on himself with soap an water hours before we left for the trip...

when you first seat a bead on a rim... you usually jack the pressure up to 30 or 35 to allow the bead to stick to the rim...

walt 'warlord' on here has also wheeled the SAME rim and 12.5 tires.. and never had a problem...


aaron's rim's were spinnign inside of the tire... bead still on there....

so. it wasnt the width.. it was the mounting surface's hadn't bonded properly yet.

[stupid]

but i didn't mount them. It was the tire shop, which uses different lube that doesn't dry nice like soapy water does, so its was worse.


after the island I had the tires aired up to 30psi while it was sitting in the garage for a week or two and I couldn't even break a bead to get the tires off the rims. I tried a hilift right on the bead with the weight of my truck and it wouldn't even budge.

Different tires and different wheels have different gripp at the bead area. Just cause a wheel says its 15 inches, there are tolerences. So lets say you get a set thats actualy 15.1 inches, it will hold the bead better than the batch that was made at 14.9 inches, and the same holds true fore tires. I've had 4 sets of 35" BFG's on my blazer, and each set held the bead differently.
