My new OEM-size tires: Vredestein Quatrac 5

[7milesout]

You already know the value Mr. Former Automotive Engineer... ULRR, lightweight and cheap as chips... done.

Nope. I don't know the value. I like numbers. And lightweight and cheap as chips doesn't hold water regarding the Enasaves. They're heavier than the Quatrac 5's and more than twice as expensive.

I might not have been clear. I don't really suppose I want to see documented evidence. I do believe the LRR claims. I guess what I'm trying to say is, I would like to see first-hand just how effective (by a percentage) the LRR effect of LRR tires are. I'm betting the LRR contribution varies depending on manufacturer, tire-by-tire (construction) as well as size of tire. Specifically, I would be very interested to see rolling resistance differences in the Enasave versus the Quatrac.

I just meant as to it being the OEM tyre de choice

Oh right, duhhhh ... I wasn't thinking. You're right about that. If a tire manufacturer could make a tire out of pure dirt that was $0.01 per tire less that the best tire on the planet, Hyundai would be the first one in line.

Basic - You are our tire expert. Would you give your best "guesstimate" of the mpg difference (in percentage) between, let's say our Mirage size tires:

• 165/65 R14 Enasaves, versus
• 165/65 R15 Vredestein Quatrac 5's

This is not a test, and I don't actually know one way or the other. I can only guess. Nobody's going to hold your feet to the fire. I'm just curious as to what YOU think, or what YOU may know.

Thanks.

The Ecopia 185-55/15 were quite close in mpg with the Enasaves, IIRC.

I'm curious if there are other tires that compare with the Enasave LRR.

Honestly there is no telling...

But taking a look... 1/32 extra tread depth, and 51psi max inflation, I am shocked the tire is a full pound lighter... that doesn't make much sense to me honestly. I bet that's not correct, but would love for Mark to weigh his when he gets them in and see for sure.

Those factors, plus the 3PMS tread... maybe 2 MPG less? It won't be significant I don't think. But you can't compare worn out Enasave numbers to new Q5s. Gotta be apples to apples.

I may be able to weigh a new 15” ecopia with oem wheel one of these days for science. And probably whatever wheel/tire combo that comes on an SE as well.

I agree about the apples!

I wouldn't be surprised if the weight measurement is wrong, & I personally don't really care. If the sidewalls are paper thin, I may not be impressed by them.

The Vredestein Quatrac 5 is a "Severe Snow Service Rated" tire. It's not claiming to be some LRR tire. I don't understand the desire to compare it to a Dunlop Enasave?

I agree that new tires should not be compared to older ones. A worn down Enasave rolls pretty good. If LRR is important to someone, they should run everyone's worn down discarded Enasave tires on their Mirage.

A couple things. I too doubt the weights for the tires on tirerack are accurate. Maybe sometimes, or most of the time, but not always. I would have to believe the Quatrac would weigh more than the Enasave. But I could be wrong on that. Perhaps the LRR does add weight.

Mark - My desire to compare the Enasave and the Quatrac is that I personally think the Quatrac to be very close to the performance of the Enasave as far as rolling resistance. It would be nice to find a redneck (but accurate) way of testing them, but it would have to be when the tires are both new or both plum worn out. Making it a difficult measurement to make for most of us. There's no way I'm going to have both new at the same time, and be swapping them out on my wheels just for something like this.

The extra weight on the Enasaves is possible, once an object at rest starts moving the heavier the object the more it doesn't want to stop. I think, all the science is fuzzy in my head.

And I have a near new set of Enasaves, less than 500 mi. on them. If someone bought me Quadtracs I'd happily take the time to swap tires around and do the testing.
