On a tire size is 205/50R15 the same as 205/50HR15....would the different letters make it the wrong tire?

Question

I dont want to get the wrong tires and my tires on my car say 205/50R15 but i have found tires that say 205/50HR15 and i just need to know I buy this tire will it be the wrong tire for my car

Answer 1

The H Is the speed rating it is rated at 130 mph/210 km/h, They will fit just fine.

Answer 2

H is the speed rating of the tire.

Answer 3

I believe the H is a rating to the tire but they are the same size.

Answer 4

H is the speed rating of the tire. H is 130 mph max speed.

Answer 5

This tire size can be represented several ways.

P205/50R15 84H is the current standard using the "Passenger Metric" sizing system.  This represents a "Standard Load" tire

205/50R16 85H or 205/50R15 86H is how a Standard Load tire sized using the European-Metric standard would appear.

205/50R16 89H would be an "Extra Load" European Metric sized tire.  An Extra Load tire has a higher maximum load carrying capacity than a standard load tire and a higher maximum inflation pressure.

All of these tires are dimensionally identical.  The differences lie in their load carrying capacities - how much weight they can carry.  That gets a bit more complicated to explain.  Some vehicles may require an Extra Load tire to obtain sufficient load carrying capacity.  To be sure I would need to know year/make/model of vehicle these are being put on. Any of the Standard Load tires are for all intents and purposes interchangable.

205/50HR15 is the obsolete way of representing a Euro-Metric sized Standard Load tire.  P205/50HR15 is the obsolete way of representing a Standard Load Passenger Metric sized tire.  A few tire companies still use this old system or might have a combination of this and the current systems listed on the sidewall.  

Any way you slice it the "H" represents the tires "Speed Rating" or the maximum speed the tire is rated for.  Different letters represent different speed capabilities - another long topic of discussion.
