Completely clueless about wheels and tires

I have a 2007 Tundra CrewMax.

The only mods I have done was to level the front with new shocks (kept the oem coils). I will be needing new tires soon. Basically I want the largest tire I can fit on the existing factory rims (18") without any mods. Looking for a more aggressive tire but still good for the road as I use my truck for work. I want the tires to be a little wider and extend past the wheel wells a bit (but not too much).

Thanks.

 

All the info you need can be found on these two threads. Welcome!

My suggestion is to start looking at build threads, and the wheel and tire thread. Also, I’m assuming you put Bilstein 5100’s on the front? How much actual lift did you get on the front end? All of these things come into play.

 

Yes I did the 5100 on all 4 corners. I would say it was about 1.5" on the front. Basically it is level now.

 

Thanks for the info. I guess there are just too many variables. I was hoping someone would say get this size tire and this size wheel.......

Oh well, more research.

 

If you want your tires to poke out beyond the fender, you will either have to get a set of after-market wheels or use wheel spacers.

If you decide to go with after-market wheels, get something like 18x9 with 30-35 mm offset. That will make the tires poke out a bit. Lower offset wheel will push out more. For reference, here is mine (18x9 18 mm offset with factory tires 275/65/18). Don't get 18 mm unless you are planning to get some fender flares.

 

I understand that. From the "largest tires you can fit" thread, I would say 275/70 would be no problem, 285/65 or 285/70 would probably be ok.

 

You can fit 275/70/18 without any modifications. You can fit 295/70/18 with minor modifications. Check some of the TRD Pro builds, a lot of those guys run the 295’s. There are several pics of 275 on stock rims in my build thread before I got new rims.

 

Thanks. So when you says "mods" are you referring to higher lifts or trimming the inner fender walls?

 

I’m sure someone who is running this size will chime in soon but whenever I was researching it I believe the consensus was that taking off the front mud flap/aerodynamic enhancer thingy and possibly relocating the fender liner slightly forward was all that is necessary. I can’t remember if these guys are running spacers or not to push them out away from the skid plate etc. but that is one of the questions I would be asking when I found someone running that size.

Good luck!

 

For the record, I have 275/60R20s (33 inch) on Bilstein 5112s (brought it up 1.9" in the front). I had to do MINOR adjustments like remove the front plastic splash guard thing, and then push forward my front wheel well liner and re-screw it in. Took all of 5 minutes and some JB weld to fill the old hole in the plastic. I now have no rub, even at full lock up hill in reverse as I did before. I can't believe I had to do anything with a lift and only 33s, but the fix was minor. My fuel wheels are a +20 offset, which may have impacted rub a bit as well.

Just my two cents, hope it helps.

 

Thanks everyone!!!

 

From what I’ve read, it seems like the more the wheel sticks out (less off-set) the more prone it may be to rub or hit the front inner fender well area or bumper or the body mount, especially with a bigger tire. For stock rims with more off-set, a wider tire may hit the upper control arm or skid plate. All this to say that rim off-set may affect rubbing as much as tire width and diameter.

I’m guessing minor mods can mean suspension lift and fender well adjustments, like heating the plastic fender well to bend it away from tire contact or removing front or rear mud flaps (or both), or cutting or bending the skid plate lip or a combination of all those things. I wouldn’t consider the cab mount chop (also called body mount chop) a minor mod since that requires cutting it and welding in a fabricated piece. It requires some cutting and welding tools and some fabrication skill.

As far as tire size goes, I agree with the above - 275/70/18, 285/65/18 are probably your best bet. The TRD Pros with their 2” front stock suspension can squeeze in 295/70/18s on stock TRD Pro rims (think they’re the same as TRD rims but fully powder coated). A few who’ve added wheel spacers to their stock TRD Pro rims for a slightly wider stance have reported some front fender well rubbing with that tire size, which tells me the stock off-set is probably best to prevent that kind of rubbing.

I will say that my 275/70/18 BFG AT/KO2s on stock suspension rubbed the little front mud flap pretty bad at close to full wheel lock with aftermarket MB wheels with less-than-stock off-set (can’t remember if they’re +18 or +25). I suspect they probably wouldn’t rub with stock rims since I’ve read of others with that same size tire not experiencing any rubbing on stock suspension.

Hope this helps.

 

Get round ones

 

Thanks.

 

Forgot to mention 285/70/18 might be another option with a mild lift. They're obviously a bit narrower than the 295/70/18s, but I believe they're also a bit smaller in diameter. Unfortunately, there are only very few options in that size (maybe 4 or 5?), which is a shame since this size is a good one for those of us who just want a mild lift and mildly larger tires. Many more options with the other sizes mentioned above, though.
