I am sure this has been asked and answered before so I apologize, but Search is not my friend tonight. What is the maximum tire size I can install on a non lifted 1985 F250 4WD.I am thinking 33's (and maybe more) will fit just fine but I don't know about the width. I really don't want a real wide tire anyhow. I have the factory steel 16 inch wheels. Thanks in advance.
I'm runnin 33x12.50r16.5's bfg all terrains they don't rub at all. When they wear out might go to a 34 or 35x9.50 mud terrain. But I have been pretty happy with my bfg's they ride well and have never let me down off the hwy. Too bad truck tires are so damn expensive, hope this helps.
I have my eye on some 285/75R16's. It looks like they run out at 33.2 in diameter fit a 8" rim with a range of 7.5" to 9", and have a section width of about 11 and a half inches. E Range. Thoughts?
I believe those factory steels have an 8" rim width, is that so?
I do plan to lift the truck maybe 2 inches but the tires are going to have to come first and I want to keep the factory steels, they are in great shape. I also would rather not have to swap gears like I would need to do with significantly larger tires. I don't have any issues with leaving the factory gears as is with only going from a 32" tire to 33.2" but a bit wider.
I am more of a lurker than a poster but I do want to say thank you for a great resource.
The factory rims are not 8 inches wide. The factory steel rims are only 6 inches wide. All those guys in the previous posts saying "there tires don't rub" can't be running the stock rim. It makes a big difference. A aftermarket rim is wider, and sets the tire away from the truck frame further which helps prevent rubbing.
OK then, second question. With the stock steel rims am I pretty much stuck with the 235/85R16 as a maximum size?
What should I look for regarding wider rims at the salvage yard, or on the aftermarket? I actually prefer the look of the plain steel rims on this truck but want slightly larger tires. I have no desire with this vehicle for fancy wheels.
If you get too wide a tire on the narrow rim, it will wear the middle of the tire out before it wears the sides. I got a good deal on some 31x10.5x15 tires for my f150 because the guy I bought them from had them on a stock toyota factory rims, and the center was getting worn down some. They would still pass inspection easily in the center, and the outer edges were like brand new. I installed them on some cheap chrome rims that were 8 inches wide, and got a lot of life out of them.
You may run into this problem also if you get a tire that is too wide for your rim, even though it may not rub.
