Hey guys I need some questions answered and I am sure I will hear plenty. In the next couple of weeks I need to have some front end work done on the truck just ball joints as I was told at my last inspection. I will also be putting some new tires on I am thinking a new set of Toyo s have had good luck in the past unless you have any other suggestions, my tire size is 265/70/17. I was also considering going with a little bigger tire if I can, along with that I`m thinking about a front end leveling kit. My truck is a 09 GMC crew cab 4+4, that fits in the garage right now.

Will a load leveling kit mess anything up put more wear and tear on any other parts?

I don`t know if I can put a bigger tire on my size rim?

Anybody do this what size kit?http://www.autoanything.com/suspensi...A6485A0A0.aspx

Any comments good or bad like to here them.

I had a red 09 Z71 with a leveling kit with 295/70/17 Toyo M/T s and the air ride rear leveling kit with on board air compressor. I also put a set of led cab lights on it with blacked out windows. I bought it new and put 88k miles on it in 2 years. Looked nasty but it did go through 2 sets of front wheel bearings. First set at 31k miles covered under warranty. I went through 2 sets of the Toyo MT's on that truck and on my second set on my dodge I have now. Best tires I've ever had and have not had to change a flat yet. Knock on wood.

I also have had the Toyo A/T and got just as many miles out of the M/T and they look a lot better.

Thanks for your reply I have monday off from work and head down for new tires I like the look of the AT`s, I only tow about a 100 miles a year may be a bit more I am just thinking of going with the regular AT and not the LT is this a mistake?

A/T= all terrain light duty semi aggressive tread, L/T=light truck any tread pattern but is at least an 8ply tire. If you tow or take any load get a LT tire. I wouldn't put a "P" series tire on a truck unless its only used to pick up Twinkies, chutney squishies and pink ribbons from your local Quickie Mart.

The ones I am talking about are the 10 ply Toyo M/T or Mud Terrain. You will never have to worry about a flat. You may think it is overkill but it's what I recommend. They also have them in a smaller size and lighter ply but I don't have experience with them. If you want a good look and strong tire it's the 10ply 295/70/17 Toyo M/T.

From what I've read in researching toyo tires, Nitto and Toyo are basically the same tire. So if your trying to save a few bucks you might price out some Nitto's to see if they're any cheaper right now. Speaking of saving a few $$ I've got Nitto Grapplers A/T on my truck and went with the non LT because of price. I've never had a problem towing my 24' boat and really couldn't tell the difference in towing from the LT BFG's that the truck had on it when I bought it. The biggest difference is the cornering ability, as obviously the sidewalls aren't as stiff and gives a little when cornering hard. But I must admit I drive like a bat out of he!!. The next set I buy will be LT's though if the funds are available. I also leveled mine by just using the stock keys in the front (no need to change keys). I set mine 1" lower in the front so that when I am hooked up to the boat it sits level.

I have a dodge 2500 with 35/12.50/17 Toyo M/T now. I'm on my second set on this truck. This would be my 4th set of these tires and over 150k miles without one single flat. The worst thing I've had is a low tire that I drove and had fixed. I have not changed a flat on my truck in over 5 years. I'm on gravel roads and very rough paved roads daily. I pull an enclosed trailer twice a month every month, I tow a case skid steer all the time, and I also pull my 24 fountain a lot. I am also in the mud regularly checking hog traps and hunting and these tires are amazing. I've never had a Nitto but I have seen a lot around and I still buy Toyo's. Cheaper is not always better. I have gotten over 40k miles on each set and I am hard on tires.

I have an '02 Dodge 2500 and went from the small standard 265/70/16 to 315/70/17 BFGoodrich TA..........found 5 Hummer h20 rims and tires for $250 on CL

I would recommend the LT, E rated over P metric, C rated for stability reasons given above.

As for the "Level". There should be a sticky for GM trucks.
I don't know what the kit in your link is supposed to do. Pic looks like nothing I have seen for a GM.
Most try to "crank the torsion bars" on the cheap. As garrett28 points out, this creates bad CV angles that will destroy front end components and shocks as well as give a crappy ride.
You need shock extenders to prevent damage or different indexed shocks. Upper Control Arms (UCA's) properly installed should restore proper angles to not completely chew though ball joints and improve ride. Nor-Cal's stage 5 is the minimum I would do - http://norcaltruck.com/index.php/com...uct/parent,16/
The heavier unsprung weight will still tax components greater, evidenced by GM upgrading pieces for 2011+ as they started installing larger stock tires. "Level" will let you run 285 or some 295 with minimal rub.
You will also see approx. 1mpg decrease due to weight and resistance.

I judged all that effort and expense just to stroke my ego on tire size, a bit too much. You decide.
