I bought a set of tires that I couldn't pass up. They are 38x13x16 front tsl and 38.5x15x16 bogger rear both on 16x8 wheels. They are atleast 95 percent tread with the knobbies still. When they were advertised they both said 38s and I never looked up the size lol. Well the fronts according to the chart say 37.8 and the rears are 38.4. Is that enough difference to tear up anything or should I swap the boggers out to a 16x10 or 16x12 wheel or just adjust air pressure or something.

probably wont matter either way, but if it was me I'd run the bogger in the rear and the TSL up front then lower TSL to trail pressure and measure from the bottom lip of rim to the ground and adjust the rear bogger to match. I have 35x16x15 boggers and even aired down to 0 psi, they don't really bulge out so you may need to set the boggers to 10-12 psi and adjust the front tsl's to match... play with it

That's exactly what I will do. Thanks
