Replace the two most worn tires, usually the fronts, and mount the new pair on the rear. But the two you keep decide if two will do.

The better tire costs less per mile you will actually drive. Real cost-per-mile math in 225/65R17, by how many miles you drive a year.

Drivetrain is only half the answer. On classic and low-mileage cars, tire age and construction decide whether you buy 2 tires or 4.

Both spellings are right. The mark on the sidewall, DOT or E-mark, is what decides load capacity, pressure, and US legality.

Track tire pressure isn't a single number. Hot targets by tire type and car weight, how much pressure rises, and when to bleed.

Swapping 245/75R16 for 265/75R16? Wheel width and load range decide whether it works. Fit, rub, load, and speedometer, by the numbers.

A stock CJ-7 runs 31s, but only if you know your axle track and spring height. Here's how to tell what size your Jeep can take.

275/65R18 instead of 265/65R18 adds half an inch of height, but the load range you pick changes your truck more than the size does.

285/70R17 fits most 265/70R17 trucks, but the LT construction and wheel offset decide ride and rub. Here's the fitment math.

275/55R20 bolts onto your 275/60R20 wheels, but the load index decides if it's safe. Here's the capacity and pressure math.

Machined, milled, mirror cut, chrome and paint: how each two-tone wheel finish is made decides how it ages, cleans, and repairs. Hank sorts it out.

Replica wheels are safe when they carry real test marks and a load rating that covers your axle. Here is how to check both before you buy.

Trailer tires usually age out before they wear out. Hank explains the 5-year rule, reading the date code, and when storage shortens the clock.

4WD or AWD only skips chains at R2 if all four tires say M+S. Here is what each chain control level demands and what to carry before you go.

Every 1973-79 F-100 is 5x5.5, but not every 5x5.5 wheel fits. Hub bore, 4x4 hubs, and backspacing decide what bolts on.

35s fit a stock Gladiator Rubicon or Mojave with the right wheels and bump stops. On other trims, and with a loaded bed, they rub.

OBS Chevy trucks use three bolt patterns, not one. Match C or K, 1500 or 2500, hub bore and lug thread before you buy wheels.
