My truck is in the shop, and while its there I want to replace the bald rear tires. I want to go one size up in the rears to 305/45/18 from the stock 295/45/18's, and just leave the 295/45/18's on front.

Now should I get the same stock Goodyears (except one size bigger) or get the Nitto 555R's in one size bigger as well? Which tire would all you guys reccommend?

I have to get new tires by tommorrow, so please help!

 

If you want to go bigger, you'll have to go with the Nittos. Goodyear doesn't make a 305/45/18 in the F1's. Not to mention the Nittos should be a little cheaper.

 

I would stick with the stock F1's
to me they are still the best tires for the Lightning
