    I’ve had several Tacoma’s over the years but never a single cab 4 cylinder 4wd. I bought this truck last week from an older gentleman that’s had it since 2010. It currently has the spacer lift and has 265/75r16s. Will it clear 285s MTs and the motor turn them ok? This truck won’t be a daily driver just mainly used on my property and around town. Thanks

    I don't know the answer but you can put tire sizes in the calculator here to get an idea of how much bigger they will be then do some measuring.

    IMO it looks good as is.

    Regearing the axles to match the tire size will help immensely with this.
    Calculate from whatever the OE tire size was (found on the door placard) for the new tires. I suspect you'll be looking at something around 4.88:1 gears.

    Stick? Sweet little single cab! Personally I wouldn't, unless you're fine with the added expense of a re-gear (X2). I run 265/70/17's on my 2.7/stick/access cab and it's fine. 4.10 factory geared I believe. A fairly taller (& heavier) tire would be pushing the limits of the 4 banger IMO. Nice truck!

    I’m on 285/75/16 and stock gears.
    Pulls just fine if you put your foot in it.
    2.7l and stock gears, with camper shell, armor, winch.
    If I went 35s I would regear. Not necessary on 33s.
    I run SPC UCAs and had to do some trimming and a cmc to fit 33s

    The 1st set of numbers determine the width of the tire's sidewall in millimeters. 285 is just one of 3 numbers needed to describe tire sizes. It's 20mm (about 3/4") wider in the sidewall than a 265 series tire. You need the other 2 sets of numbers to determine the tires height. A 265/75/16 is the same height as a 285/70/16 and about 1" taller than the stock 245/75/16 tires. 265/70/16's were factory option on some trucks. They are the same height as a 245/75/16 but about 3/4" wider.

    IMO a 285/75/16 is pushing things even with the bigger 4.0 engine. 265/75/16 is a good compromise. It splits the difference between stock and 285/75/16 and isn't so big that it hurts performance or requires mods to the truck.

    It depends on how much power you're willing to give up. I'd rather keep the performance of a slightly smaller tire and sacrifice the 1/2" more ground clearance I'd get with a 285/75/16 vs 265/75/16. 285 series tires cost a lot more too.

    Not worth it for 3/4" more sidewall width. Remember, this is SIDEWALL width. Not tread width. There is no standard measurement for tread width. It varies by manufacturer, and you just have to check the manufacturers website. Some 265 series tires put more tread on the ground than some 285 series tires.
