Bigger Tires

I have an E '99 F350 Stock Suspension. It needs new tires but I was looking to get something bigger....How big of a tire will fit without rubbing up against the leaf springs at full steer?

If its a 4x4 then you can go with 305's and be O.K. if its a 2wheel drive then go with 285's. A 4x4 can be leveled in the front for about $50 (2" lift) a 2 wheel drive is a little more expensive, but can also be leveld up to 2" in the front. you should have 4" blocks in the rear since your truck is a 350, if not, Superlift 4" rearblocks, and new ubolts can be had for about $100 from 4 wheel parts dot com

Yes it is a 4x4 so I will go with the 305's and invest in the leveling kit. Thanks bdrummonds

ok so I just searched for some 305s and came up with a few but I noticed that the Max Inflation Pressure was 65psi. I know the stock tires are 80psi. Is that gonna make a huge differance? is so should I stick with the stock tires instead?

I thought it was the rating that mattered not the PSI required.

I have stock size now (10 ply), and will upgrade to a 285 8 ply that will full fill my needs.

I believe D rated tires go to 65 PSI and E rated go up to 85. You want E rated if at all possible.

My 37" toyo m/t's are 10 ply e rated and max is 65 psi, so I guess it depends on the tire...................

It does depend on the tire, my 35" Fierce Attitudes are E rated and max pressure is 80. You definatley want an E rated tire if you are going to do any towing. A 10 ply tire provides more lateral stabilty, and makes the truck ride better in my opinion
