Eagle F1 GS-D3 (confused RE: Z or Y speed rating)

Goodyear's site states this tire (Eagle F1 GS-D3 ) is a "Y" speed rated tire. Period.

Tire Rack states the same tire comes in various speed ratings.

I've called around locally to get various quotes. Wal-Mart has the best price and offers road hazard (others in my area do not offer road hazard for this particular tire). However, the rep @ Wal-Mart says he shows the tire as having a "Z" speed-rating, but a "Y" load rating. Now, I'm definetly not an expert. Interestingly, the pic on tirerack.com's site show's "ZR" on the tire.

What I'm asking is, are there different ratings for the same "model" tire (Eagle F1 GS-D3)? I just assumed that the "GS-D3" denotes a certain standard, but that doesn't jive with tirerack's statement. Is there a particular part number that will guarantee that I'm ordering a 245/50/16 with Y-speed rating?

The reason I'm asking is that none of these places have the tires in stock and they'll have to order them. Wal-Mart has the best price (less than $700 driveout with road hazard).

Thanks.

Since it only lists the Y speed rating for the size you were looking at I would have to say the tire is available in many different sizes, some of which are available with a Z rating, but the size you're looking at isn't.

Like the Tire Rack page says, the tire comes in three different speed ratings and the rating depends on the size of the tire. The 245/45-17 obviously comes only in ZR and 245-50-16 comes as Y-rated.

There is no such thing as "Y load rating", so the guy at WM doesn't know what he is talking about there.

Regardless, you will not notice too much of a difference between a Z- and Y-rated tire, so if you are getting a good deal on them w/road hazard @ WM, I'd definetely take them.

Most definetely you will end up with the exact tire you are looking for. ;)

Good luck! :)
