Will a 285/60/18 and 285/50/18 fit my 99 Lightning and run okay??They are a whole lot cheaper than the F1's

 

I'm running 285/60/18, and don't have any problems with fitment. However, I'm not happy with the 1.5" they lift the truck. I thought I'd get better gas mileage, but I actually get worse. They change the 3.55's to 3.21 effective axle ratio, and the 3.73's to 3.37's. There also isn't that much difference in the ride.

The 285/50/18s sidewall is only .4" taller, so it won't make much difference from the original. (3.55->3.45; 3.73->3.63)

 

i thimk i saw someone running a 305/45/18 if so does that mess with the height and gearing

 

I wouldn't go taller than a 50 series.

And the 305/45R18's are within a hair's breadth of the stock F1's in terms of height.

 

Ive seen them on a L and have to say thats too much sidewall for me. Looked like a mudtruck or something. THe nitto 555' have a nice sidewall.

 

How much cheaper can you get tires that size? You can get a stock sized 295-45-18 made by Hankook for $146 per tire from this link if you are looking to save some money.

 

I got two for the front today!! I love them. Got dr's for the back.

 

Im enjoying the DR's while i can the 20's should be here anyday now. I have the regular 555's comming on them.
