'18 Platinum - Going From Stock 20" to Pro 18" Wheels - Question

Hello,
I have a 2018 Platinum with the stock 20" wheels on them. Truck is bone stock, no lift...spacers...suspension mods...etc. I do currently have 275/60/20 tires installed onto the stock rims (I believe stock is 275/55/20).

I recently purchased a set of 18" TRD Pro Forged black wheels. Anyone have any suggestions/know what the biggest tire size I could put on these rims would be? Also, any suggestions as to wanting to push the wheels/tires outwards just a bit simply for looks...not much, maybe an inch?

Thanks,
Blake

 

this is where i got my tire info:

copy pasta, should check out link though for more options and pics.

Second Gen (2007-2013) and Third Gen (2014+) Tundra
No Lift Kit
Max tire sizes are:

• 18″ rims: 285/65 R18 – 5/10ths taller and 4/10ths wider than factory. Trimming may be necessary.
• 20″ rims: 275/60 R20 – one inch taller but same width as factory

Without changing the wheel, the only way to get them further out is to use spacers. But then you may have rubbing issues depending on what size tire you go with. I swapped out my Limited's 20" wheels for another stock design but 18". I have 285/60 without spacers.

 

Thanks! That's pretty much exactly what I wanted to know. As that sits in that photo, is that stock....ie no lift, no suspension mods, no spacers, etc.?

Thanks man!

 

Correct. All stock except for the wheels which came off of another Tundra. I got them off of Craigslist but do not know what model, year or trim. I bought them because I wanted 18" wheels and these match my MGM.

 

Forget that "max size" thread. You can fit much larger tires if you are willing to make clearance for them. My 325/65r18s (35x13) on 9" +25 rims fit with no lift and zero rub.

You should have bought different rims if you want them more outboard...

Look at 295/70r18 (34.3") and 285/75r18 (34.8"). These fit on your stock rims and require minimal work to keep them from rubbing. If you make them stick out farther (using spacers), more work will be needed. Or you could run a smaller size.
