Upgrade to Big Rig tires

It's about time the 01 CTD SRW got a fresh set of tires put on it. These last set of Firestone tires will end up getting me around 18,000 miles. I plan on keeping this truck a while so I have been tossing around the idea of uprgrading to big rig tires. I know that the initial cost of wheels will most likely be in the $1,500 to $2,000 range and tires will not be cheap either. But from everyone I have heard from said I will get anywhere from 80,000 to 115,000 miles on a set of tires.

In my head it makes sense, if I can get tires for a tire for slightly more then stock tires I have now then I can make up the price of the wheels pretty quickly by not having to buy a set of tires every 10 months. I've also talked to the guy at the local tire shop that to save some money initially I could put a set of retreads on the rear. I am looking to go from 265/75/R15s to a 265/70/R19.5 (or 33.6").

But I'd like to get some real world experiences from you guys. Fuel mileage affects? Ride affects? etc.

To hell with mileage. Basically, it will go from a plush ride to an endless rail road crossing.
I drive both kinds at work.
Firestone is the problem.

Ah gas mileage will be non existent.

What is the matter with yuh. I can get 70k miles from a set of 300$ tires so I don't see the savings here buddy....

Yeah, if you're only getting 18,000 miles out of your tires, there's something wrong. I can get 40,000+ on my '03 4dr, longbed, 4x4 Cummins. And it wieghs more than your '01. Your truck doesn't have 15's on it either as you said in the 1st post. It'll have 16's.

I'd take a look at cumminsforum.com and browse around there. LOTS of good info. Hollar if you need any help.

Look for "E" load-rated tires in the original 16" size. The more plies on the tread the better. I had an old dodge truck that ate through tires in about 18K like that (driving it up and down canyon roads in the mountains outside LA didn't help), and the harder tread compound on the E's held out for more than 50K.
