Is it bad to run 2 different size tires?

Having two different-sized tires on the same axle is generally not a good thing. If the diameter of the two tires is close, then the rolling radius is about the same, so in the short term, you probably won't have any damage, but long term, you run the risk of messing up your car's differential.

Is it OK to drive with different size tires?

Having different sizes on some four wheel and all wheel drive vehicles can actually do damage to the vehicle. Since tires vary from brand to brand, and even from model to model, damage can even occur with tires of the same size if they have a large enough difference in circumference.

Is it OK to have 2 different size tires front and back?

No matter what type of vehicle you have, having mismatched tires front to back can sometimes cause handling problems. Granted, this really doesn't happen that often, and it is usually no problem to have different tires on a car.

Is it safe to drive with mismatched tires?

We advise against driving with mismatch wheels and tires. Mismatched wheels and tires can cause premature and uneven wear and tear on the new and remaining three wheels. Even replacing a single worn out tire with a new one, could mess with the handling of the vehicle because of the different tread depths.

Will different size tires affect differential?

With two different size tires there is a difference in speed even going straight down the road. This will over-work the differential and harm it very quickly.

Is it OK to Mix Tires on a Car or Truck? Old

Is it important to have all 4 tires the same?

Because the front and rear tires of all-wheel drive and four-wheel drive vehicles perform different duties while accelerating, braking and cornering, tire rotation is important to even out, and maintain equivalent treadwear of all of the vehicle's tires to minimize potential driveline stresses.

Can wrong size tires damage transmission?

Increasing Tire or Rim Size Can Cause Premature Wear

If you are running an automotive transmission this can cause some serious strain depending on the current gear ratio if you choose not to re-gear your system.

What happens if one of your tires is the wrong size?

A: The mismatched tire is a dangerous situation. It should be replaced with the proper size immediately. And they have placed the tire on the worst possible end of the car, the rear. Mis-sized rear tires can lead to a loss of control under hard braking (the car can spin).

Can mismatched tires cause transmission problems?

The condition of tires is as important as maintaining your car. Following are some of the drivetrain components which can be damaged due to mismatched tires: Engine. Transmission.

Can mismatched tires cause vibration?

Uneven tire wear can cause your wheels to become unbalanced and unbalanced wheels shake your car! This can be difficult to diagnose but a skilled auto mechanic can find the problem in a flash. Proper maintenance can prevent most shaking and vibration.

Can you have 2 different tires on your car?

Is It OK to Mix Tires on Your Vehicle? The short answer is that, in general, manufacturers do not recommend tire mixing at all. For optimal safety and performance, it is recommended that vehicles are fitted with the same tires to every wheel position on your car.

Can you run different size tires in front and back of car?

What happens if wheels are different sizes. In a front- or rear-wheel-drive vehicle, as long as both rear wheels are the same and both front wheels are the same and the suspension geometry is set up to accommodate this, the vehicle will operate fine.

Can I mix tire sizes?

Don't mix tire sizes. All four tires must be marked with the same tire size unless otherwise specified by the vehicle manufacturer. This also applies to winter/snow tires. Don't mix radial and non-radial tires.

Do tire sizes have to be exact?

Width and diameter are the two factors that determine tire and rim compatibility. For diameter you'll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17" diameter wheel.

Can I use 245 tires instead of 235?

The quick answer is yes you can replace 245/50-18 tyres with 235/50-18 but they will have 10mm (0.4 in) smaller overall diameter. Will only slightly effect speedo and odometer - ie speedo will read about 1.5% high.

Can you drive with one tire smaller than the others?

You can drive with a smaller spare tire but not more than 50 miles. Smaller spare tires are not meant to travel for a distance more than 50 miles and speed exceeding 50 mph as they have a much smaller size and little to no tread compared to normal tires for better traction handling and ABS control.

Is it OK to buy 2 tires instead of 4?

If two of your tires wear out faster, it may only be necessary to replace those two instead of replacing all four. If you do, it's important to have the two new tires installed on the back and the partially worn tires moved to the front – even on front-wheel-drive vehicles.

How important is it to match tires?

Matched tires = more even wear

In addition to maintaining control and stability, having a uniform set of tires lets you rotate them regularly. This helps the tires wear evenly, extending their life and making the most of your investment.

Is it OK to replace only 2 tires?

If you are looking to replace all-wheel drive tires, we recommend replacing all four at once. While it may be tempting to replace only two at a time, mixing new and worn tires can create a size difference from front to back, which can lead to damage to your vehicle.

Do you have to have all the same tires?

Unless you find yourself in a circumstance where you absolutely cannot get four of the same tires, it's important to have matching tire brands and styles on your vehicle. Mixing and matching can lead not only to vehicle damage but also accidents on the road.

What happens when you mix tires?

Uneven tread wear

Mixing tires prevents the even distribution of weight across the four wheels. Unless you remove the odd tire, it's going to cause some tires to wear out faster – even if you rotate tires or keep them aligned.

Do 4 wheel drive tires have to match?

Drivers with an AWD vehicle should refer to their owner's manual for specific guidance on tire replacement. It's always best to use four tires from the same brand—and the same model—on a vehicle. Unless specified by the automaker, tires should be the same size and have the same speed rating and load index.

Can I use 165 tires instead of 175?

Yes, you can replace the 165 tires wit 175 tires. The circumference of the 175/65 is slightly smaller so your speedometer will read slightly lower than it did before for any given engine speed.

Should the best tires be on the front or back?

According to Tire Review, new tires should always go in the back. Rear tires provide the vehicle stability, and if they have little tread, then stability is lost.

Is it illegal to have different tyres on the same axle?

No. Mixing different tread patterns across the same axle is not allowed. The identical tyre model and tread pattern must be fitted for a single axle. You can, however, use different tyres on a separate axle – just as long as they too match each other.
