Ok guys, here is a question.

right now i have 4 tires in poor shape (31/10.50/r15)

i dont know what the rim size is :confused:

i need 4 brand new all terrain tires to go on my 1986 Chevy K5 Blazer 4WD :k5:

i have been told i can go up to 285's, is this true? :dunno:

I am adding 2" blocks underneath to raise her up a little as well :weld:

so any tips on how big i can go without looking stupid :screwy:

PS I will have pics of her this weekend for all to see:p:
 
The r-15 means its on a 15"rim. Size depends, there is a post up top about pictures with tire sizes on trucks. a 285-75-15, depending on manf., is around 32" tall. 32-12.5-15 (285-75-15) usually fit stock in all-terrains with non-sagging springs.

Don't forget......if you dont put the stock dia. of tire back on, your speedometer and odemter will be off.

I noticed this when i put the 39x18x16.5 mickeys under my rig:D

yeah i thought about that. i do plan on going a little higher with blocks and tires. i dont think i will need to adjust the speedometer at all, but i will check that with another vehicle as i drive
 
anyone know of good brands? :dunno:

i have heard to stay away of firestones

here is a list i have come up with of brands :wink1:

input please :p:

Michelin, BF Goodrich, Goodyear, and ProComp

We do have a 4wheel parts in fresno but they are ****ing expensive:mad: :haha:
 
we looked under the front leafs and there are no blocks at all

i know i can add them in the back for a 2" lift but i didnt know you can add them in the front as well
 
Well, you can't add them in the front. Well can but... anyways. It is highly unsafe to use blocks on the front axle, and the DOT for most states consider them illegal for use on any road with front blocks.
 
bfg all terrains always look good on regular blazers in my opinion, also BFG and michelin are the same company (as is bridgestone and firestone), just michelin are a little more expensive for the same tire casing, its basically the tread design you look for between them

that helps cool
 
Not questioning if you have them already or not, just advising not to add them. Only reason I brought it up was because you said you were going to add 2" blocks, and I wasn't sure if you were implying 2" body lift blocks, or axle.
 
i dont know exactly what your talking about sorry. all i know is that they are blocks you can add by the leaf springs
 
Sorry to confuse you. Body lift blocks go between the body and the frame, thus lifting the body, and the other kind are the blocks you are talking about that go under the leaf springs.
 
goodyear MTR's are good tires. I have over 41K miles on mine. Firestone are not bad tires, they got a bad rap because FORD was underinflating them on exploders. because of that ALL new cars(not just ford) built after 2008 will have standard tire inflation monitor systems. just what we needed, more electronics.
 
I'm partial to the BFG allterrains myself. 32-11.50r15 should fit with no rubbin' and maybe 33's. Also have to agree with blocks between the front axle and springs is a big no no.
 
Check Wally Marts prices when you go to get tires. If you find a good price in a mag and decide to try 4WP, take it to them and tell them you will buy the tires from them if they give you their price and they forget shipping (they will charge you) since you have to pay tax. They usually bite with out a prob on that. America's Tire is a good place in Fresno to get tires as well (there is like 3-4 locations). Consider a General Grabber too, not a bad tire in my opinion. There is a spring company down town by Grizzly Stadium that will re arch your springs for like $80, I have a set of 2 1/2 blocks you can have for under the rear springs, I might even still have U-bolts too.

wow, thank you so much. i will consider your offer.
 
You know what I learned , if you actually ever wheel at all , and catch the "disease" . Those 33's will be too small . And when you go up another size again , 35's , and wheel once , those will be too small too . Its been a month , and I am already dreaming of 37's..................and I am about to pay off my discount tire card too :yikes:
