215 vs 225 Tires: Rim Diameter Their rear tires have a larger diameter compared to the smaller diameter in their front wheels. Based on this explanation, you are likely to find 215 tires changing roles with 225 tires on different vehicle types because the 215 tires have smaller diameters than the 225 models.

Firestone’s 215/60R16 tires fit a wide range of vehicles and are built tough to provide durable and dependable performance for the road you want to explore. A popular size for the Honda Accord, Toyota Camry, Dodge Caravan, find the right Firestone tire for your mid-size sedan or minivan below.

They have to meet size standards for bead shape, diameter and width. Wheels and tires must be of the same diameter– e.g. only mount a 16″ tire on a 16″ wheel. However there is one other caveat– wheel width and tire width.

215 and 225 are tires that are supposed to fit with different width for their unlike sizes. True to their name 215 is a bit smaller and has less width. On the other hand, 225 gives better grip due to its broader width with better surface coverage.

They’ll definitely fit alright… I even ran 215/60/16s (rather than standard 245/50/16s) on my factory 16×8 Firebird wheels in the winter without a problem.

The 225/65R17 is one size larger and much taller and can carry more weight compared to the 215/55R17. The ride will be harsher as well as the aspect ratio is two sizes lower. The smaller tire will fit on the same rim.

You will have to change the wheels. The last number in the tire size designates the size of the wheel it will fit onto. If the tires on the vehicle are 215/55/17, the vehicle has 17 inch wheels. The 215/60/16 tires will only fit 16 inch wheels.

B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.

Re: P225/60R17 vs P215/60R17 They are interchangeable.

If you are have a 205/50-16 tire and want to install a wider tire, you can install a 215/45-16 tire. The side profile is expressed as a percentage of the width and therefore needs to be smaller as the width becomes larger in order for the outer profile to remain the same.

For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.

Thus, some cars have wider tires in the back than front. This is not typically done for front wheel tires, they loose grip to easy as they get “back heavy” under acceleration. However, once you are rolling, wide tires slow you down!

In practical terms they are usually no more effective and in some cases less effective than their skinnier counterparts. Mud is one of the biggest areas where wider is definitely not better. Take a look at this video of a mud truck. Tall, skinny tires backed with insane horsepower.

It depends on how deep the mud is and the type of mud etc. If you CAN get to solid ground without sinking so far in you are doomed, a skinny tire is better. But if you can’t reach solid ground you want as wide as you can handle to sling more soup and stay on top.

MUD. The benefits of a narrower tyre are well known in muddy conditions, where a thinner tyre is more likely to cut through surface mud and find firmer ground below. Fortunately, most muddy roads are only surface deep, so there are definite advantages to fitting a narrower mud-terrain in areas of high rainfall.
