hey all,

my 86 sr5 came w/ steel 15x6 steel wheels w/ 225/75r15 and the tag on my door jamb only covers the steel wheel...

what tire came stock OEM on a truck w/ the 15x7 alloy option back in 1986?

thanks

I am pretty sure my '86 4runner (bought it in 1986) came stock with 225's on the sr5 15x7 alloys...might bump up to a little bigger 235 pizza cutter...

hmmm, i thought they might have come w/ a larger tire 'cause of the larger width of rim, and the upgrade?

i like your 81 trekker btw. I always like those older ones a bit better

I think that was the only tire size available up until the 31x10.50 tires that came on some trucks in the early 90's. They used the same 15x7 alloys. Although, I don;t think Toyota ever changed the door jamb sticker to match the actual tire size.

The tire/wheel package (not exclusive to the SR5, but most common) was for 235/75-15's

Essentially a 30" tire - so if you'd like to maintain a 4.10 then 235/75-15 or a 30x9.5-15 would both work well. Plus the 235/75 is a great size for pricing/availability of tires.

How about this tire! A yokohama y742s is a pizza cutter tire w/ a diameter of 29.8". I like the skinny tires for my region. They do best up here in CNY. I used to have 33" x 9.50" BFG MT on my jeep cj. They did great!

The Yokohama Y742S are the only narrow tires i can find other than the Interco 215/85r15's. The swampers are too heavy and gnarly for what i'm looking for.

Here is a link to the specs on the yokohama's: Y742S specs

So here is my question:

I have some stock 15x7 alloys that i just bought and would like to use. I could not find any 15x6 alloys. Will the Y742S be alright on the 7" rim when the max recommended rim width is 6.5"?

thanks

I've been looking at the above tires and also these: 215/75r15, 225/75r15

If i can get the Y742S 7.00X15 to fit on my 7" rim ok then i think that's the best of both worlds. It's a pound lighter than the Toyo Open Country AT 30x9.50 and it's a commercial rated tire w/ a long wearing compound. Plus it's narrower size aids in better fuel economy and traction where i'll be using them.

However the 235/75r15 is 5 lbs lighter in the toyo OC AT. Rotational mass is important to consider, though i think the 22re will have no problem spinning the weight of the 7.00x15 or 30x9.50 alloy rim combination.

I'll stop blabbing now, happy holiday and good new year!

A 235/75-15 is a 29" tire. Just my two cents.
