After 37,000+ miles on the stock BF Goodrich Rugged trail tires, I was finally able to justify new tires to my wife. I installed new BF Goodrich KM2 Mud Terrain tires on my '07 Tundra in May. The 35x12.50x18 tires mounted up fine on the stock TRD wheels. I had to trim the front skid plate about 1" and no rubbing. The I have Bilstein 5100 shocks on the highest setting on the front. With the lift and tires, the truck now sits exactly 4 1/4" higher than stock.

Ride: The larger tires ride noticeably smoother at speed compared to stock size (for instance, cannot feel lane markers as you run over them). However at lower speed (parking lot) you can feel and hear the buzz from the larger aggressive lugs. Highway speed noise is minimal but noticeable over stock.

Off Road: The limit (before the nannies kick in) comes much at much higher speeds than the stock on loose gravel roads. Mud clears well and I can make it places in 2wd now where 4wd was the only option with the stock Rugged Trails.

Gas Mileage and Power: I installed the Hypertech Speedo Recalibrator after running without it for two weeks. Before installation the gas mileage on the truck computer showed right around 14mpg average compared to 16.7mpg that I had before the tires. After the Hypertech unit went in, it is reading 16.3mpg average. The speedometer is spot on when compared to GPS speed. I recommend hypertech if you change tire size. Seat of the pants power is still there. This truck pulls.

Nannies: The VSC kicks in at lower speeds than stock on off ramps as others have similarly reported when going to larger 10 ply tires. Zero point recalibration at the next dealer visit to fix this.

Nice to see someone else do it smart with the hypertech, good job. Truck looks good!

You don't have any lift on the rear? Whats different on the TRD Off-road package that gives it lift?

 

[dogstate]

That thing looks awesome.

How is the wear on it? How many miles do you think you'll be able to get out of 'em?

Do you mind sharing us the price/tire as well as overall price? Thanks.

Any muddy pics?

Truck looks great.. Can't wait for my stock bfg's to wear out. 30,400 miles and 6/32nds remaining.

That tire isn't cheap in a 35! I'm glad your wife approved! :tu:

I'm also wondering about the rear end lift of your truck.. 1" block?

Morning Glory: Thanks. I paid $1,370 out the door at 4wheel Parts in Portland with road hazard warranty, mounted/balanced, etc. I have about 2,000 miles on them so far and the tread still looks brand new. No telling for sure but I'm told they are good for right around 35-40,000 miles. I'll post some mud photos after the next outing. Tundras do look good in the dirt.

Lakaiguy and Picjon: No lift on the rear. I just did the front with the Bilstein 5100s to level the ride. Plans are to get some rake back with a 1" block and upgrade to 5100s on the rear when I have the extra cash. I have to sell that to the wife also.... need it for towing the RV, hauling firewood, etc... Any other selling points would be appreciated!

Mhollack: I left the USB cable attached on the hypertech for later programing without taking the dash apart. I think it was you that shared that tip on a previous post. Thanks.

Dude, you STOLE those things.

What did you pay per tire? Tire rack sells them as a set of 4 for MORE than what you paid for them.

Ya.. If you get some more rake in it with the 5100's.. Tell her it will make it easier to park because you'll be able to see over the hood better.. ??? Maybe she can drive it lol.

Just tell her "it'll make these expensive tires last longer, especially when towing so the truck sits level.. Otherwise the tires won't last 20k miles and we'll have to buy more! You don't want that do you?? Me either!"

Haha.. Good luck in selling it to her!

Yep! Too good to pass up. They were $315 each...after some dealing.

Excellent selling points! I'll let you know if it flys!

It's great to see a thread that provides an answer not a question, especially when it comes to tires. Points sent and I love the set up. I may actually consider those tires next time after seeing your pictures.

Quick question: Does the programmer actually improve the mileage, or did it just fix the computer to output the mileage?

I hand calculate my mileage and with my new 35'' Trail Grapplers, I have been getting around 12.7 mpg. Will the programmer bump this number back up some? Am the miles I am usung now in my calculations correct, or are they off due to the tire size?? I know the speedo is off, but is the odometer off as well?

If the speedometer is off, then yes the odometer is off as well. You are not getting 12.7MPG and are probably driving a lot more than you think.

... my new 35'' Trail Grapplers...

what wheels are these mounted on? stock Toyota? if so which? I see that Johnny Thunder has them on the same stock TRD wheels I have on my 2010. I like the look of the Nitto Trail Grapplers so would like to see what they look like on a stock wheel.

Any pics of yours? TIA

Not on stock wheels. I had to trim the body mount and shave off some of the front bumper. I also removed the front lower inner fender for the time being.

20x9 +12offset Incubus Crushers

Crappy cell phone shot. The center caps are now on.

THANKS for the quick reply! Sweet looking tires and wheels.
