i can only find 3 tires in those sizes on tirerack and tires.com

where can i find these tires online?

There is a fairly limited availability in those sizes, it seems most make the big jump from 285s to 325s. If you google the size, you should be able to find the different tires available in that size, once you figure out what you want, then you could try giving tirerack a call if you can't find a reputable site that carries them.

295/70r18 are available from Nitto and 305/70r18 are available from a few other brands.

305/65r18's okay? i can get them in a bfg at, they are 33.7 inches, 325/65r18 is too wide im guessing but thats a 34.6

What rims are you using?

If you're staying stock, the width is more important than the height. Take a look at this thread: https://www.f150forum.com/f4/tire-wh...04-08-a-24510/

ive seen that, i just didnt know how the metric widths worked out. i know its 305 millimeters wide, but i mean with the rubbing at the uca part. ill be using the stock 18 inch lariat wheels. cant find any wheels i like on a blue/tan truck

12.5 inches is 317 millimeters, and i know a km2 has a small enough sidewall that it wont rub the uca so anything wider than 315 will rub the uca im assuming.

The results with 12.50s rubbing or not vary so much on here, probably your best bet is to put the kit on and then measure before ordering tires.

Your stock tires are probably 275/65R18s, so you could measure your clearance at full turn at droop once its on, and order based on that (1/4" order 295s, 1/2" order 305s...).

good call. but 35s and 3.73s wont prematurely wear out my trans?

I'm sure it will have a minimal effect on the longevity of the tranny, but I doubt it's anything to be overly worried about, especially if you get a tuner sometime in the future that causes a better shifting pattern for the transmission.

so 35x12.50s are fine as long as i use a tuner to change the tire size?
