The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.
Can you use 235 tires instead of 225?
Can 225 fit 235 tires? Yes, they can. 225 tires are 10 mm narrower and 15 mm lower in height than the 235 tires. Besides, 235 tires are wider than 225, and so we recommend checking the owner’s manual.
Does tire size matter on a car?
Does Tire Size Really Matter? Simply put, the larger your tire, the more of a grip your vehicle has on the road. As a tire’s width increases, it covers more surface area on the road. That being said, a vehicle with bigger rims will often be able to fit larger tires than other vehicles.
What does 50r mean on tires?
50 is the two-figure aspect ratio. This percentage compares the tire’s section height with the tire’s section width. For example, this aspect ratio of 50 means that the tire’s section height is 50% of the tire’s section width. R indicates the construction used within the tires casing. R stands for radial construction.
What do the 3 numbers mean on tire size?

Should I change all 4 tires?
Some manufacturers of all-wheel-drive vehicles recommend that all four tires be replaced, not just one or two, because a new tire will have a larger overall diameter than the other tires. The best approach, though, is to replace all four if the tread on the old tires is significantly worn.
How much difference in tire size is acceptable?
When changing tire sizes, we recommend staying within 3% of the diameter/height of the original tire. Any more than this and you face the risk of brake failure.
Can I use 235 60r18 instead of 225 60r18?
Yes they will be slightly wider and will have a slightly higher diameter.
Can I replace 18 inch wheels with 17 inch?
No, a tire with a 17 or 18″ diameter will not work on a rim with a 17.5″ diameter. Putting a 17″ tire on the rim will tear it up and the bead will not seat if you attempt to put the 18″ tire on the rim. You will never get it to take and hold air.

What is the advantage of 19 inch wheels?
The 19-inch wheels definitely look the coolest. But the 17- and 18-inch setups offer a better compromise of grip, acceleration, price, and ride harshness, so we’re not surprised VW uses 17- and 18-inch sizes on its hot Golf, the GTI. If it’s acceleration you’re after, stick with the smaller, lighter wheels and tires.
What does 98 mean on a tire?

What does R17 mean on tires?

What is the difference between a 60 and 65 series tire?
The 65% aspect ratio (as in 235/65/17), compared to 60%, adds almost 12 mm (1/2″) to the radius of the tire (0.65-0.60)*(235mm)=11.75mm.

Is it OK to replace only 2 tires?
Mixing tire brands or even different models may cause handling instability. And when replacing only two, we recommend installing the new tires in the rear and placing the (older but still decent) rear tires in the front. This may help prevent a spinout or oversteer condition on slick roads.
