Can anyone help me out? How big a tire on my F250 stock rims?

I'm getting ready to put new tires on my 2008 F250 Super Duty.

Stock rims are 17". Tires on it now are 265/70/R17. These are, I think 31.6" Diameter when new.

I want to go to a slightly larger tire on same rim and not add any lift. Would like to gain an inch of ground clearance. At least. The existing tires look to small, but I don't want to spend more money on bigger rims either.

I have done some research and am looking at 285/75/R17 for size. They spec out at 34" or 33.9" depending on Tire model/manufacture.

Can anyone tell me if these will work?

 

Trying to keep cost reasonable, but when you go up in size of tire you go up in $$$$.

Currently looking at Yokohama Geolander A/T GO15. 285/75/R17

 

I've had those tires on a truck before Well Seasoned . They are a good tire. I am sitting on 17" rims right now. So I'm wondering if there would be any clearance issues with the 285/75/R-17. You know how the big companies are about staying original size, etc. So if I go on tire rack or other large tire websites and search for tires by putting in my truck it won't give me bigger sizes. So I'm looking if someone would know if these will be okay. I think they will. But you know how things can go sometimes when you start thinking.

 

You can probably buy a leveling kit relatively cheap and that should allow for a larger tire.

Most are saying 35's.

Largest tires to fit on a stock 08 on 20's?????? - Diesel Forum - TheDieselStop.com

 

Ya. But that's on 20" rims. I have the factory 17".

 

Looks like I may have to add a 2" lift if I want to go 34" or bigger without any rubbing. Still researching.

 

No help here, but I saw your truck in another post...Very nice truck!

 

I think you do need a small lift to go 34" Gas. Wheel size doesn't matter much, just width & O D of the tire. If you go to a narrow 285 tire you might just make it. If you increase tire size, your speed sensor can be reprogrammed to that size so the speedo/odometer read correctly.

 

Tire Size Comparison

IF you can drop down to 16" rims ( calipers may not allow it) there are a lot of cheaper options.
A few tire capers still retread 10 ply 16" tires with some deep aggressive tread at better $

 

I run the geolander a/t on my f150. They are a great balance. Most time they are perfect. About once a year i wish i had muds, but these wear great and ride very nice too. The bfg at is another good choice as well as the wrangler duratrac. I shop at discount tire direct as i mount my own tires. its easy to find tires cheap when you don't need mounting etc. in fact up until two years ago my 8year honestly didn't know most normal people didn't mount their own tires with irons in the driveway not to mention the starter fluid to seat the bead!

 

Stock 18" 275/70 R18 are a touch over 33". You may get away with the 285/75/17 with no rubbing

 

I’ve got a 2006 f250 that has some after market 17” rims and 33x12.5/17 tires. They were all new when I bought it a couple years ago. They look cool and are good for floatation in mud, but super noisy and Not great in the snow on road since they are so wide and that type of tread. Also they are load range D which doesn’t help much when overloaded with wood. As far as fitting they never rubbed and fully turned there’s just room for me to get my hand in there. Keep in mind though my after market rims might be a touch wider and have a different offset than factory. I’m due for rubber the end of the month and will be going 285/75-17 I’m thinking. A touch narrower and a tiny bit taller

 

I've owned 3 Ford Super Duty's since '06 and I can definitively tell you that:
1) you can do a 33" tire without issue or modification.
2) Daystar (and other companies) makes a leveling kit consisting of 2 poly blocks that sit on top of your front spring. It's an economical option that literally takes 15-20 minutes to do, and 35" tires will now fit. With the large wheel well of the Super Duty, a 35" tire does a lot to improve the aesthetics of the truck. I did this option on my '06 and was very happy- in full disclosure, on a steep downhill driveway into my favorite lunch joint, as I cranked the steering wheel all the way to the right I got a tiny amount of rubbing. It was only in that place and I didn't feel that I needed to trim out any material from the wheel well.
3) If you lift the truck, a 4" lift will take a 35" tire without modification or a 37" tire with significant trimming. A 6" lift will take a 37" without trimming.

 

for snow narrow is better, those big wide tire just turn into snow plows. I do not really care for sounding like a freight train running down the road either. Mastercraft( division of Cooper) Courser atx not a bad tire- particularly when being price sensitive

 

I ran the BFG All Terrains on my two previous trucks, and liked them a lot. Even with how heavy the Super Duty is, I got 55,000 and 58,000 miles out of the KO2 tire from BFG.
Then I got bit by the big truck bug, from watching re-runs of The Fall Guy. I've crossed over to that side, with 6 inch lifts and 37 inch tires. Went with the Toyo mud terrains, strictly for aesthetic purposes.

 

I have an 08 f250 that I’m running 315/70/17 stock rims and no lift no rubbing. Mickey Thompson ATZ P3.

 

I'm too short for tall trucks and tires. I keep them reachable.

 

Good! If you are running those with no rubbing then the tires I ordered should work without any lift or leveling kit.

I did some more research and Monday morning I ordered the Yokohama Geolander A/T GO15. 285/75 R-17s. I ordered them from discount tire direct. They had them in stock and said 2-3 days. Should have them Wednesday or Thursday at the latest. Appointment made for Friday to have them mounted, balanced, and an alignment done.

 

I have lifted two trucks with two inch kits and slightly larger tires. This gave me the look that I wanted and didn't raise them too high for loading. I use my bed a lot and don't want it too high.

I'm hoping to have no rubbing of tires on the F250 with these tires. But I figured if I did I could go with a leveling kit or small lift. But I don't think I'll need one.

I'll take some before and after
