305 65 18 stock wheels

Does anyone run 305 65 18 on stock 2019 Tundra Pro wheels without issues. Specs on wheels are 8” and ridge grappler specs require at least 8.5” wheel but I’ve seen them on Tundra Pros with stock wheels on other posts.

 

Of course you can do it, it'll just tend to distort the tread at normal pressures... wearing out the center a bit sooner. If you don't have spacers, you might be touching the UCA, which would be a no-go... possibly skid (easy fix), and swaybar (remove it?) as well.

Why not run 295/70r18?

 

Thanks. Wasn’t sure since discount tire guy said there was a possibility of tire coming off the bead since wheel was to narrow and it wouldn’t sit right. I couldn’t find a 295 ridge grappler.

 

If you really like that model, they come in 285/70r18. 34.0" diameter. Easy fit.
