I'm purchasing a F150 XLT 4x4 SuperCrew this afternoon. The dealer has agreed to a tire upgrade from the 255/70/17 Tires on the truck. Can I fit 285/70/17 (33.0 Inch) tires on this truck with out ANY modifications?

This has to be done today. So any help would be great.

 

Yes those will fit no problem, however their are a limited number of tires in that size.

 

So what's the biggest I can go without the lift or leveling kit?
Can I get 35x12.50/17's on it ?

 

What year is it? If it is an 04-05, you will need a 2.5 inch leveling kit. If it's the old body style they will fit, but barely.

 

Sorry, Its a 2005 Supercrew.

So without the Level Kit I can get 285/70/17 BFG All Terrains on the 2005?

 

Yeah, you can fit 285/70-17's (33x11.50) or 33x12.50-17's on it stock. If you do install one of the 2.5 inch leveling kits, you can fit 35x12.50's (315/70-17) if you mount them on the stock wheels.

 

Yes, they will fit

 

So If I do upgrade to the 285/70/17 All Terrain Tire. This truck is leased so if something comes up as a warrenty issue ( Transmission,Ball Joints,etc) will my warrenty be voided and not honered because I placed the larger tire on the truck?

 

No, they can't legally void your warranty, especially if they install them.

 

Are you 100% Sure? I'm going to have enough trouble paying for the lease. I would not want to get stuck with a transmission bill.

The Dealer will not be installing them now. They have the truck calibrated for the 265/70/17. I want to put the 285/70/17 on at my own will.

 

I say they can't legally void the warranty because of the Maggnuson/Moss Warranty Act. However, that does not mean that some dealers won't try to. Members here have had very different experiences with dealers. I've heard of dealers trying to void warranties because of one inch taller tires, like you want to install. However, other members have had Ligntning tear up at the drag strip and had them towed in with drag slicks still installed and had no problems at all. I would ask your dealer. If they tell you they will void your warranty, your best bet is to find another dealer. Just be sure to tell them that you know they are violating federal law and you will be sure to tell all of your family and friends about their illegal practices.

 

The thing is we are in canada...are the laws the same...i have the same truck ordered that colin has. im putting the 2.5inch lift on, with some other small stuff...and just not telling the dealer about it....and take it back off when the truck goes back to the company.

sup colin!

 

 

Still on the hunt for tires. Is It possible without the Lift to fit Goodyear MTR 305/70/17 (34") on the 2005 Supercrew 4x4?

Thanks to everyone for the input.

 

33" tires are the biggest you can go with the stock suspension. If you install a Daystar 2.5" leveling kit, you can fit up to 35" tires on it. See Senior?
