"P" rated tires on a truck are great if you only haul passengers around, go to the grocery or to church on Sunday's, but if you work your truck doing any hauling, towing or go to any construction sites or do any offroading you may want to stick with LT tires. On my '97 150 I had crappy Goodyear AP tires and had 3 flat's in 10k miles. My last 2 truck's have had LT tires and knock on wood I've hadn't had any flat's with them going on construction sites and the terrible road's around the New Orleans area. Just food for thought!

 

What he said! I still have the factory Americrap P rated on mine and they ride and handle like a luxury car when I'm empty, but when I haul something or pull my trailer they are way to squishy to be considered safe even with higher than the recommended pressure. The LTs will ride rough but last I checked it was a truck!

 

Well, I doubt I'll be towing anything major anytime soon, and my offroading is minimal right now. I would love to get some Toyo AT's but I want to wait until I get different wheels.

I get a bit of a discount from Firestone and the Dueler's are a great tire. Unfortunately, I can't find an LT in the 285/70R17 range in the Revo's. 265 is as high as it goes.

So if I have to drive in a P rated tire for a year or so, I don't mind. They will easily get me through a winter comfortably until I upgrade again.

Thanks for the input!

 

I've got a set of LT285x70x17 Toyo AT's for a spare set, and the only knock against them as that they do ride a little rough but boy can they take a beating! Suprisingly my larger BFG AT's ride almost as smooth as my stock P275 tires.

 

my dad has the toyo oc ats, 285-70-17 on his 04 ram and they ride like a caddy on it

 

I know my speedometer is gonna be all messed up going from 255's to 285's but will I be doing any serious damage until I can get a tuner? I was under the impression that yes, the speedometer would be off, but it wouldn't be like a life or death thing.

I also saw in another forum that my shifting is gonna be all screwed now too.

IM SO CONFUSED.

 

Murk, if you have the 5.4 engine with a 3.55 or 3.73 rear the 285's won't hurt at all. A tuner will help your shift points and can re-calibrate the speedo if you want to get one.

 

Whew! Sorry to ask so many questions, I just don't want to make a HUGE costly mistake. And yes I have the 5.4 with 3.55's.

Thanks!
