I just installed a winch bumper on my truck and it is sick... now my tires look to small so let me tell yall something. A while back i put some toyo MTs the size is 275/70/r18. I was very dissappointed with these tires they are waayyyy to skinny i want to know whats the biggest and widest tires possible that can fit on a 08 pro4x leveling kit and 1 inch block in rear... (I DONT CARE IF THEY RUB ILL FIX IT)

Can anyone tell me how to add picss?????

Looks good!
As for tires, wider ones get pulled in at the sidewalls by narrow rims, so if you are using stock rims, it could look a little better but not that much IMO.

For example, you could get the LT295/70R18 in the Nitto Trail Grappler M/T, at 34.6" but less than a half inch wider than your 275's on the stock rims. Or Toyo has a 33x12.5R18LT which is about an inch wider on the stock rims, and half an inch shorter than current.

But with 275's you can only go up to an 8.5" width rim so they will only get 0.2" wider at the sidewall. But with a smaller backspacing you can get a much more aggressive look, (along with more likelihood of having to trim at the pinch weld).

With the 33x12.5's on a 9" rim with 4.5" backspacing, the rims outside edge would be 2" farther out, and the tire would be 12.3" wide instead of the current 275's 11". Since they're a 33.0" might not be too much trimming.

With the 295 Trails on the 9's they would be about 11.93" wide, and 34.6" so you'd have a lot of trimming, and it might affect your torque converter locking into OD when it should. I get this with my current 34's with the BT gears, (same ratio as yours).

I also looked at the specs on the BFG KM2 M/T in the LT305/60R18, but like of lot of the 305's they are not true 33's, and it is only 32.6" diameter, a full inch shorter than the current 275's.

If you kept your 275's and stuck them out an inch and a half with wheel adapters, or got 8.5" rims with a 4.75" to a 4" backspacing, they would look a lot more aggressive.

You could fit the 33x12.5" Toyo w/o a wheel adapter and no trimming, but by sticking them out an inch or inch and a half they would look much more aggressive, and add a little stability.

The torque converter allows the truck to shift into overdrive and drops out of OD for hills. But when too tall of a tire is used it can mess up when it locks and unlocks. On my Titan 33.5" Toyo M/Ts were fine but not my 33.98" Nitto Terra Grapplers A/T's ... after reaching speed it doesn't lock up right away. In more severe cases, like when someone runs a 35 with a 2.94 gear ratio, (non tow package, OR, or PRO-4x), the Titan can shift out of OD for even slight hills).
With a 2wd, aftermarket gears are available, but fronts are not out yet for 4x4's, and the 1st ones look to be 4.10's or 4.11's which are too high of a ratio, (low of a gear), for 35's, unless you don't mind high RPM's even in OD. We need 3.73 gears for 35's. So from here on out I plan to stay with 33.5" diameter max, until there are gears, and they've been proven for a year or two.

You can get programmers and other performance mods to take care of the loss of power that a larger tire diameters cause by change the overall gearing, but gears is the only thing I know of that will trick the torque converter into thinking it is running stock. Performance mods will also help with the Toyo's or Trails heavy weight.

35/12.50 is the biggest tire you can fit with a leveling kit. You may have to "massage" the pinch weld area a little though...

Wheel spacers make rubbing worse at the pinch weld. They are only good for stopping rubbing on the suspension, like spindles, and some inexpensive UCA's, or for those rims that have their spokes rubbing on the brakes, like with my Black Rock Viper's. A wheel adapter would have worked for me instead of grinding them, but wheel adapter are the only ones I would run and they're an inch thick, so my pinch weld rubbing would have been way worse.

I've been running 325/60/18 terra grapplers on stock five spokes since last march. There was no rubbing at all anywhere on the fenders or on the suspension. I recommend this size just for the simple fact that you wont have to invest anymore effort in making them fit. One month ago i put on some black pro comp 7033 18x9 with a 0 offset. They rubbed bad so i just trimmed the pinch welds and now the clearance is perfect. I have a cheap daystar leveling spacer which is getting trashed for some bilsteins this weekend. Can't wait. I also have air rides in the rear and they had to be adjusted to clear the tires with the stock rims.
