whats the biggest size tire i can fit under my stock bronco fullsize,i dont have the running boards.need some advice fellas  

have tried anything besides the stock?i had a friend put 32 wout alift  

i ran 33x12.5 on 10" wide wheels with no issues. it was a 302 bronco single shock front and heavy factory coils. if you have dual shocks and factory coils 32's are max.  

I'm going to have to argue about only fitting 32s on a 3/4 suspenion. My 89 f150 has 33 on the duel shock front end and i beleive that i could fit 34s if i had to. The 3/4 lifts the front some thing like 1 3/4 inchs over stock.  

who said anything about 3/4 suspension,was refering to a bone stock 19 year old 89 bronco. argue all you want if you put 34's on a factory stock f-150-bronco they will rub off road  

I could fit 35's under mine with a little finder triming at the frt. adn back corners.  

I understand with some trimming,but the question was "WHAT ARE THE BIGGEST TIRES I CAN FIT UNDER MY STOCK BRONCO"? I can fit 44's under a Bronco if a take a saw-zaw to it. I just answered the question to keep from having tire rubbing. My 79+89 33's no rubbing my 94 32-11.50 stock wheels rubbed at full lock. If it is equiped with factory dual shocks it has the lightest springs available from the factory,they are about an inch lower than single shock springs and about an inch and a half lower in the front than one equiped with factory snow plow package.  

If you have duel shocks on the front then its a heavy duty 3/4 ton parts. If its only one shock then it a 1/2 ton. I had the 1/2 ton changed out for 3/4 ton. I'm not talking about the leaf springs in the back or any thing else.Ford did make a heavy duty bronco with the 3/4 ton suspesion from the fact.But if there the original one's then they have dropped some.  

yeah 34s will rub on a bone stock bronco. I didnt say that. My 150 has add a leafs and 3/4 suspion parts in the front. If i made it look like I said 34s could fit a stock 89 bron' Im sorry.
