Hey, I have the stock mag. rims on my 91 yota and was wondering how wide of a tire can be safe mounted on those narrow little rims. I'm intrested in a 32x11.5 tire but dont want to spend a bunch more money on rims. A 32 shouldn't require 4:88 gearing but If I do not a problem, I can just swap w/ my dad, he's got 4:88 with 30 cause it used to run 33s. Thanks for any help.

A 32x11.5 is pushing the stock rim. You say they are mags? All the older toys i have seen stock were steel wheels...I might be wrong. I was gonna have some 32x11.5's put on my stock rims one time and all the places wont put them on a 7 or 7.5 inch rim and if they did put them on they wouldnt warrantee the tire. Thats what i ran into.
But the best thing to do is check out your tire shop of choice and see what they can offer you. If they wont install the tire thats due to a liability issue. If thats the case you can just bring your rims in there and say its for a farm truck and then they will do it for you most of the time.
We have always done all ours ourselves and just taken them to get balanced afterwards. Its not too hard to mount them. The only pain is settin the bead and that takes a beadblaster a lot of the time or a ratchet strap around the tire.

The rims come stock on SR5s and usaully see them on
4-runners. I have a set of steel 16X8, what would be a tire close to a 32, 285/75 ? I dont know mucha bout that type of sizing. Is it metric? What ever, I'll see what I can do.

They are steel rims, unless they are aftermarket

Im pretty sure that Ive seen stock Toyota wheels that weren't steel. There kind of a bit odd looking. Kind of like a cross sort of design look on them. I dont really know how to describe them. Ive seen them a few times. Mostly on SR5 models.

SR5s came with aluminum rims, i know because my 4runner is one and has them. They are 7" wide and you shouldnt have a problem running an 11.5 on them. Im running 37x12.5s on mine for three years with no problems. Heres a pic, its a few years old, the old girl has been painted since.  |

I had my tires mounted by the place i bought them, Goodyears Canadian chain Fountain Tire. They did an alignment as well for twenty bucks. It was funny watching the alignment guy test drive it around the parking lot with a big shit eating grin on his face. They never said anything about warranty issues or mounting problems, in fact they gave me my warranty card and told me i could come back and have them rotated for free.

the bigest problem in tire/rim width is going with narrow tire on a wide wheel it isnt so bad to use a narrow wheel with a wide tire and some ppl like to use a a narrower wheel that the tire manufacter recomends cause it help protect there shiny new alumies from rocks and stough and helps the bead stay seeted
ive done it both ways and and let me tell you that a 30 9.50 15 on a 10'' wide wheel is about the stupidest thing i ever did see but i wanted the wheel's on my truck and thay were the widest tires i could find that day it was a pain in the butter to mount them took 3 guys to mount them 2 pushing down and 1 puting air in. the tire michine's air blast was no match for that combo
ps most tire manufactures recomend a wheel 1-2 inches narrower than the tire width

Yea I have the SR5 rims. I just picked up those 16" steel rims for free today and I mesured them and there only 7" also. I like the look of the steel rims better and I plan on mounting new tires on them instead of the SR5s. So your saying a 11.5 or 12.5 tire can be safley mounted. What about airing down for snow?

Airing down is all good. The narrow rim actually holds the bead better at lower pressures then a wider rim would.

You typically use a rim 2" or so narrower than the tire width, ie 8" rim = 10" tire. People into rockcrawling frequently use a rim 4" narrower than the tire cause it acts as a poor mans beadlock when airing down low. Putting a 11.50 tire on a 7" rim is really pushing it, a 12.50 no way. Doubtful you could even find a tire store that would do it. |

i run 32 11.50s on a 7" rim and have had no problems, it still looks plenty wide to me. my dads buddy at the dealership mounted them for me and he didn't complain any about mounting the tires. when my dad was into four wheeling he and his buddy both had 14/35 Gumbo Monster Mudders and his buddy ran them on 7" wheels to give it that tractor tire feel under the fullsize ford
