using a 215-65-15 tire in place of a 215-60-15....is it ok?

Question

my car usus a size 215-60-15 tire,would a 215-65-15 size be ok ? i know that would mean the 215-65-15 would be a little less width but it would be minimal,only one size difference.

Answer 1

another goose!
215/60-15 means 215mm tread width. 60 % aspect ratio (sidewall is 60% of tread width). fits 15 inch rim

215/65-15 means 215mm tread width. 65 % aspect ratio (sidewall is 65% of tread width). fits 15 inch rim

second tyre has larger sidewalls and therefore is a taller tyre. width is exactly the same

Answer 2

215 60 15

Answer 3

The effects of going from 215/60-15 to a 215/65-15 will be mild. 60 to 65 means 5mm taller side wall. The overall tire height will be increased 10 mm, but ride height will be 5mm taller, or 1/5 of inch.

The effects on the speedometer and odometer are minimal (usually 1-2 mph @ 60mph) and much is based on gearing of the trans and differential. But 1/5 of an inch is no different then going from new thread to a bald tire...

Taller sidewalls are better for ride comfort(more air between you and the road). So the tire may make the slightest bit difference in the smoothness of the ride.

BUT out of everything, do not run just one 215/65-15. Match the axle (both rears or both fronts same size). That 1/5 of an inch will offset the suspension if you only do one tire.

tirerack.com is a great site to see if the difference in tire-sizes will affect your car's speedometer and their answering service will know if tire clearance will be a problem.

If you open any particular tire on this site, you will see the word spec. Open that page and to the far right there will be a column heading - RPM. In tire language that means revolutions per mile. What you need to do is compare your exact tire RPM with the tire of your choice that's been up-sized to 215-65-15. I've already picked a random tire (Yokohama TRZ) and the difference in revolutions rolled per mile is 27. Generally speaking a difference of 20 RPM's or less won't appreciably affect speedometer readings.
215-60-16 = 823 RPM. 215-65-15=796 RPM.
Your speedometer will slow down about 1 mile an hour because of the larger circumference of the 215-65-15 tire.

You may be able to match up something much closer with another brand of tire but I didn't know what your brand and type was.

Answer 6

The tires are the same width, the difference is in sidewall height with the 215/65's being taller. This is turn will throw off you speedometer and odometer readings and gearing. My advice, as always, is to use the tires the car was engineered for. Strange things can happen when you change sizes.

Answer 7

In terms of change to 215-65-15, i suggest you change the rim to 16" or 17" if you want to lift you car higher.

60 works fine with all vehicles, but it will be a bit slippery when you make cornering or drive fast. Increase the Width will make situation worse, less accerarate power. (may be save a bit gasoline if drive on highway) If you want better handling, you should reduce the width to 215-17-55" in stead.

Answer 8

It will be ok but you should replace all 4



From a Service manual:

Under certain circumstances, a vehicle manufacturer may recommend or permit a specific optional tire size, type, inflation pressure, maximum speed, maximum load, etc.
􀂃 Never select a tire with a smaller size, or with less load carrying capacity, than the tire specified on the vehicle tire placard.
􀂃 Substitute tires should never be inflated below the pressure shown on the vehicle tire placard.
􀂃 Never exceed the maximum load capacity and/or inflation pressure listed on the sidewall of the tire.
􀂃 Never exceed the maximum load capacity and/or inflation pressure of the wheel.
􀂃 Never utilize an unapproved wheel or one that does not meet the approved rim width range for the selected tire size.

Answer 9

You will get uneven wear on all 4 tires if you use it for a long time.

Best bet is 4 matching sized tires.

Answer 10

it will be fine as long as your replacing all 4. if you are just replacing one, do it only for temporary until you can get one the same size as the other 3.
