Talking Recomendations for Tires

I would like to raise my truck up with out going the whole route of a lift kit. I have had numerous suggestions, the biggest one is just get bigger tires. I dont know how large I can go with out possibly causing performance issues or maintance issues. I know if I go too big, not only am I going to be required to lift the truck but also may cause a ratio issue that will eventually destroy the truck from the underside.

What would be your suggestions for a AT tire? I live in Central TX and would like to experience off road but obviously not enough to decide when I bought a truck to go with a 4X4 or All wheel. So the tire would need to be aggressive enough to allow for some off road but also allow for an ok ride on the road, since that is where it will be used the most.

The OEM for my truck is 18" rims but I had that increased to 20" chrome rims, currently with 275/R5520 Pirelli Scorpions. Also with your suggestions on tire size, what would the increase in height be? All the suggestions will be greatly appreciated.

I have 18s and I have 285/65/r18s on my truck. They're BFG AT T/A KO. Other than the the fact that they're having issues balancing them right now, they've been flawless otherwise. Been through some small mud holes, traction on wet grass is superb and even on dry mud holes they're a lot of fun lol.

Stock that came on my tire were 275s. My truck went up .5" b/c of my tire switch (total of 1" diameter diff but /2 that's .5 of actual lift).

You can most likely get away with 33's (maybe some rubbing issues??) but anything smaller should work out well.

Would I have to adjust down to R5020 to keep from rubing on turns as well? 33's would be 305/R??20 or actually 315/R??20 size tires? I dont remember.....

Well the first number is the width of the tire. So 305 is in mm. Let's say 50 is the second number. That's the height in percentage of the width in sidewall. So there is 50% of 305 mm for the sidewall. Then you convert that to inches, multiply by two (two effective sidewalls between top and bottom), plus the size of rim, let's say 20". That will tell you how tall it is.

I can speak for Tundras, and not F150s here, that 305s will sometimes rub on the skidplate.

So, for now your tires (275/55/r20s) are 31.9" tall. Realistically, you want to go to like 33.2" tall tires. That would be the 305/55/20s. The 285/65/20s are 34.-" tall. My tires are 33.2" tall I believe and they're a solid fit (wish they were a tad bigger though) but still look great.

Unfortunately the 305s are like $50 more than the 285s.

Wheel_Calculator : This will help you find out what tire size is what

3 Questions for you:

1. 4x2 or 4x4? I think I'm reading that you are 4x2
2. How much $$$ you looking to spend?
3. Belton, Temple, Killeen area? I'm leaning towards Killeen based on your screen name.

anyways, on eBay, you can get a Leveling kit for $69-89 bucks. the 4x2 coil-over is ~1" shorter than the 4x4 coil-over...so the relative amount of "lift" is different.

4x2, you can easily install the 2.5" or 3" kit. This will allow you to fit 33-34" tires on stock rims without rubbing. Some M/T tires will rub slightly, but 99% of A/T tires WILL NOT

4x4, should only go 2.5". This will allow you to fit 35" tires.

I recommend Autosprings Leveling Kit. I've got it installed on my truck, and it is high quality...and cheap. You have to order their stuff off eBay though.

The install is easily done in your driveway with hand tools and jackstands. About the hardest part of the install is paying for the alignment. There are some before/after pics in my gallery.

hope all that ^^^ helps you
