Default Legacy GT OEM RE-92As vs WRX OEM RE-92

Legacy GT OEM RE-92As vs WRX OEM RE-92

Does any one know if either tire is "better"? I know the legacy is in 45 series and 17" Z rated- so that implies that it is a higher performance tire than the 16" 55 series V rated WRX OEM tire. Does anyone know from experience or from testing results perhaps how these tires behave differently. Does the re-92A that is on the Leg GT pale in comparison to other Z rated all seasons?

I'm aware of the countless posts that bash the WRX oem re-92s... but this is a different topic.

I've tried to search but with no luck.

I don't think the speed rating difference would be enough to significantly change the performance of the tire. Speed rating mostly relates to internal construction so the Z rated tire may be slighly more reinforced than the V rated, but I wouldn't count on a noticable difference. It is also entirely possible that the V rated tire could achieve Z ratings as well but simply aren't badged as such to fill in a market segment (in other words, tires may be manufactured to the highest spec and simply sold at different speed ratings to satisfy the market.)

Other areas like tread compound and pattern will most likely be unchanged.

Interesting... i wonder what Luke from tirerack says about this. What you say makes sense, however It seems weird that an S rated 70 series tire may have similar performance to a Z rated. It just seems that the combination of a lower profile and higher speed rating tire would probably improve performance.

Well, yeah, lower profile is going to improve steering response and be a little more resistant to sidewall rollover, but you are only talking about 12mm less sidewall here. Most tires of a particular model come in a narrow band of sizes so you aren't going to be comparing a 70 series to a 45 series.

Speed rating itself is not indictative of any performance enhancements. Really, there isn't much functional difference between Z and V rating anyways. Both are 149mph, it's just that Z doesn't have a defined upper limit because it's an older rating (149+mph).

I find it odd actually that the tire has a Z rating, that implies that it was tested awhile ago since Z ratings are depricated now and replaced by V, W, and Y.

Yeah the RE92s go from 70 series to 45 series according to tirerack. I'm thinking that the re92s that are on the legacy will probably be marginally better than the re92s on the wrx, mostly because of sidewall, and less so because of speed rating. It would be nice if we could get more input from drivers, but alas this forum is one of the fewer traveled forums.

I have driven on both and although I can't specifically state that the difference was in the tires, they produced far less noise under similar conditions in the Legacy GT than in the wrx. I was surprised that they had as much grip as they did on his Leg.

I find it funny that people bash the Re92 as they do. I bet everyone that bashes them has not gotten a performance alignment. The tires don't seem bad at all after that.

Well, the legacy GT has better sound dampening for one if you are talking about road noise.

If you are talking about noise when pushed, the contact patch is going to have different characteristics due to the tire being wider and more weight with the legacy.

RE92A's are defintely better. kinda like getting hit by a bus is better than getting hit by a locomotive though...

dry traction is a joke. I mean on a road that alternates between wet and dry depending on the tree cover, the car never changes line when changing from one to the other.

Wet traction is kinda scary as while cornering is the same, there is ALOT less traction under power and braking. So you can't use the throttle to alter line safely.

My guess would be that they are just as sucky as the WRX RE-92. What's the treadwear rating on them....the WRX's was 160 I believe....horrible. Also in last month's Car and Driver comparo (which included the Legacy GT), it's braking distance was dead last of the group of 4 cars compared...the "legendary" Re-92s are most likely to blame for at least part of this deficiency.

The RE92's on the 05 GT are good for what Subaru wants them for - to provide a balance of handling, wet, dry, winter, summer, etc. Spent yesterday (all day) driving in and around the West Virginia mountains (including unmade roads) - it was, wet, rainy, misty, you name it. No tire issues at all - was I going 10/10ths? Nowhere near it, but to do so on the public roads is pretty stupid. For going noticeably faster in the twisties than most everything else under those conditions though, the tires were fine.

To the point about comparing Legacy fit with WRX - the car set ups and NVH management are so different that you are comparing the cars, not the tires. Only way to compare tires accurately is back to back on the same car - preferably tested "blind", so the driver does not know which set he is on. That way you get unbiased results absent the "buyer emotion" that comes into play when you have laid out money for something and have to belief it's OK.

There are too many compromises on a AWD car that many will use as a winter car and family car. In my opinion Subaru should continue to offer the RE-92 as a reasonable jack-of-all-trades, but should offer a performace tire as well that would surely improve summer / dry / wet performance markedly. They are probably scared folks will use them in the snow anyway.

Since when are the STI's RE-070's rated for M&S? Subaru already offers a performance tire.....just not on anything except the STi. They are not worried about STi drivers and snow.

Many manufacturers are offering a non-all-season tire choice now, so it seems logical that SOA should do so.
