Hey everyone my first post im excited lol. As in other forums i have used the search function but i didnt find exactly what i have been looking for.

The truck is a 1999 extended cab long box 4x4 7.3L the tires on it now are a LT265/75 R16
Now for the question the ride height is stock, and i would be using the stock rims that came with the truck,

how big of a tire can i go i was thinking that a 275-285 wouldn't be too much bigger but at least fill the wheel well in a little bit

Thanks again and this is a great site

 

I put BFG AT 285's on my stock rim and have had zero issues. They fit fine!

 

ProComp Mud Tires, Low Prices on Pro Comp Mud Tires these are the pro comp that i was looking at or else i was thinking mickey thompsons

 

I run Michelin LTX M/S 285s and I have no problems of them rubbing and they really give the truck a nice stance and fills in the fender wells. ALot better then the factory 235 tires.

 

What they said with the addition of WELCOME TO FTE!!!! glad to have you and dont be a stranger! The only dumb question is the one that doesnt get asked....

 

Well thank you for the nice welcome everyone and thanks for the quick responses

 

285s will fit just fine. My Dad is running those on stock rims and stock height and I had those on my truck before I leveled it. I'm running Dick Cepek FCIIs. I really like them, take a look at them.

 

I can't remember where I saw it but there's a chart that shows lift vs. tire size. You can go up to 33s without a lift (285/75-16). I'm sure you can fit 35s under there too with stock height but you might have some rubbing (recommended 2" lift).

You might want to consider getting some new rims too. I've seen guys run up to 315's on stock rims (they look like balloons). The tire shop can fit just about whatever you want on a rim, but depending on the size, you can lower the tire life. I'm not sure how wide your rims are (mine are 7") but I would assume that they are 6-7". that's fine for 265s and just in there for the recommended width for 285s. The recommended wheel width is 7-9" for a 285 tire. The narrower the wheel, the more rounded the tire will be on that wheel. You may not see it, but it's there. You will want to play around with tire pressures to keep from wearing down the center of your tread prematurely because of this bowing. Just something to think about.

I'm going to get 285s my next go 'round too to fill up the wells a little better, but I'm going to get a set of 16x8 wheels for them too. The tires will last longer and the wheels will almost pay for themselves in the long run, at least that's what I'm telling my wife...

Just my .02

 

I am running 285s on 16x8.5 rims. Like said ^^^, tire life can suffer if you run too large a tire on the stock rim. I can now run the proper tire pressure for the load, now that things are sized to match. I also have a leveling (add-a-leaf) kit on the front, so I have no rubbing issues.
Actually, my wife encouraged me to get "nicer" rims when I looked at getting the larger size.

 

Welcome to FTE. Lot's of very good people with great insight into these trucks around here. It is going to depend on how good of condition your springs are in. My truck is 4 years younger than yours and I ran 305's on stock lariat rims, without a lift with absolutely no rubbing what so ever.

However, there is NO WAY you will be able to run 315's (which are basically 35's) on a stock stock wheel or a stock suspension without rubbing. I have 315's on Pacer rims now and a 2 inch leveling bracket in the front and a 4inch block replacing the stock 2 and half inch F250 block in the rear and the drivers side front tire rubs the fender liner a little bit when I am turning.

 

A guy I work with runs BFG AT 295's and they rub alittle.

 

285/75/16 BFG AT TA's on my stock 99, no rubbing and so far I'm very pleased with the way the tires handle/perform.

 

I found some Pro Comp Xtreme All Terrain Radial LT285/75R-16 for $179 each and a set of 4 shock absorbers that are pro comp also for free or the mud terrain for $202 a piece with the free shocks also

 

i have 285 geolanders, so far the best tire i have had for wet/snow/ice. i have yet to put some decent mileage on them to test the wear. They also have very little road noise.

 

I'm on my second set of 295's and haven't rubbed at all. The only problem with that is that 295's are not very common.
