talk to the dealer and make sure that changing the tires doesn't void the warranty......changing brands wont but sizes might. anything they can do to not have to pay for it, they will.
-also you can get the truck lifted without voiding the warranty. it will prolly cost a little more to do but yes you can do it. all you have to do is have the dealer do the lift, then its covered by them. i would ask them about that too. or atleast thats how chevy dealers in michigan operate. good luck

 

Odds are you can probably do 265/75/16's. I used to have a Stock 1995 Dodge Ram 4x4, and was able to put on 285/75/16's, with a little bit of rubbing in you cranked the wheel as far as it could go. Dodge seems to have a little higher stock height, but maybe you can do 285's as well with a little bit of rubbing.

 

yeah, i work with one guy that has a big dodge, and one guy that has a big ford. dodge's lift blocks in the rear are slightly larger than the fords.

 

you can fit 285's on a stock chevy with zero rubbing if your putting them on stock wheels!

 

Asking this on the Ford Forums for 97+ trucks like your Super Duty would be a good start. Chances are that would be where people who own similar vehicles would hang out.

Oh, read the first post in this particular forum. The one titled "DO NOT POST VEHICLE SPECIFIC QUESTIONS HERE".

 

I would assume that they should fit. My '99 Super Duty has that size on it right now, and I still have all kinds of room. This is on the Factory rims. However, mine is a '99 with the V-8 so there may be some small differences that wouldn't allow them to fit, but I doubt it.

Also, as far as I know they cannot void your warranty for adding any aftermarket equipment unless they can specifically show the equipment caused the failure. This came from a certified GM mechanic (my cousin). He said even if they can prove the aftermarket equipment caused the failure it still dosn't void the warranty, they just will not cover the costs of that repair.

 

if they aren't covering the cost of the repair than WTF are you paying more for warranty for? just to get screwed over by the dealer.....if they put it on they cover it. why is this so hard to comprehend? grrr

also being the dealer will give themselves the descretion to decide what caused what, dont you think they will blame anything you touched to not have to cover it?

he's not talking about if the dealer installs something. he's talking about if he installs something... outside of the dealer's consent, i guess you could say.

but, the dealer must fix anything under warranty no matter how you modified the vehicle...like lift kits and such. if the dealer tells you they cannot fix the broken truck under warranty, they must PROVE that the aftermarket part is THE reason for the broken part. if they cannot prove anything, they do not have a leg to stand on and they must do the work as warranty work.

dealers will always bs customers with modified vehicles in an effort to get out of doing warranty work. they're there to make money, and how is the dealership going to make money if they have to fix stuff for free??? so you see, they want you to have to pay for the repairs and they'll try lying, hoping that the customer doesn't know about warranty rules.

this is the reason so many aftermarket parts have the phrase "will not void warranty" written on the box.

i don't know about "discretion" about what part broke what - either it did, or it didn't. and if it didn't or they don't know, then dealer fixes for free. if it did, then dealer must prove the modification broke the truck and then they can legally refuse the work under warranty.

 

Dealers work for "FREE"? HA. They don't work for free. They may not get the $75.00 per hour like they do working for the customer, but they DO get paid from the manufacturer for doing warranty work. If something breaks, they gotta fix it. But, it may take some talking sometimes.

There was the guy who broke his transfer case coming down a hill. 4X4. Down a hill. In 4 wheel drive. They finally agreed to fix it. Duh...

 

"free" was hte relative term i used meaning the customer doesn't pay the dealer. did you miss that concept?

 

my brother has a borla cat back on his ta, his oil pump failed and the dealer said "the exhause you have placed on the vihicle restricts flow and increases back preassure, and thats what caused the oil pump to fail", too bad i wasn't there, i would have laughed my arss off right in the guys face, but a friend of my brothers did that for me, they packed the ta back on the trailer and took it to another dealer, they fixed it with no questions asked.

 

seriously, its all hit or miss but no dealer is your friend. i just dont want the guy (or anyone) to get dicked over when its too late. cover your arse and get it lifted with knobby tires.....thats what we all want. good luck

 

go to your local Discount tire Co./ America's tire Co. and they will be happy to measure and test fit the largest tire possible.
