Hankook RS4 vs RT615k+ longevity (Page 1 of 2)

RS4 for me lasts x2 as rt615k+

I get 4 races out of rs4's before they start to lose grip.   They still have a decent amount of tread.   A lighter and or slower car could possibly get 6-8 ish races out of them before cording.

I have frequently found this^ person to be succinct and direct in their responses.

Ok

That's a tricky one as so much depends on context and nuance. Although it is tempting to employ a straightforward antonym such as "lengthy" in light of the etymological origins of "succinct" from "sub" plus "cingere" or, if you will, "to cinch underneath" in the sense of girding or shortening an article of clothing in preparation for action, this doesn't necessarily capture the full flavor of its use in modern English. Terms such as "long-winded" or "garrulous" come to mind, but those typically refer to speech instead of the written word, except metaphorically, of course. There are similar issues with "voluble" and "windy" as well. "Prolix" or "wordy" aren't bad, as they certainly can be applied to the written word without objection, but "prolix" is verging on the status of archaism these days, as is "turgid." The latter doesn't necessarily refer to length as such, but excessive ornateness, so it should only be used with due care. "Discursive" is a good choice if one wishes to avoid blatantly pejorative connotations, or "palaverous" if one wishes to be deliberately obscure. I could continue but I'll keep this brief so as not to ramble.

Soooo, the Dustbuster could get 5 races with test and tune out of 8 tires and 4 emergency spares for another race on RS4's.  Azenis, two races out of 6 tires with two emergency spares.

'47 Plymouth  2 full races with test and tune out or 4 tires and not a damned thing left on RS4's (no significant camber wear with that car) with the rears getting greasy by the end of a warm second race.  Azenis we only have one real data point in that we could not have finished our second race on 6 tires...but since we lost (yet another) T5 cutting 4 hours out of our race, we squeaked it out.

Thanks for the replies all! Good to that the consensus is about 37-100% more life out of RS4's. Even at their worst case (37%), RS4's are still the way to go.

Only if you buy their 'sticker' tires directly from their website.  I don't have a problem with that as it is cheaper than tire rack for me.  Why can't Lemons get us a tire deal.

I think we've been through about a dozen sets of RS4's and they all seem to finally die by chunking rather than cording... but usually this is at the 40-50 race hour mark at 2-3/32nds, so no complaints.

Crazy that they let go that quickly. I haven't seen any of ours "chunk" quicker than other batches, so I'm not sure about the potential quality/batch issue. Maybe something about their setup just doesn't agree with RS4's? On my TA car, I delaminated a set of A052's, which this compound isn't known to do at all. Every other compound, including RT660 (which is known to delaminate) wears perfectly on the TA car.

I like some of the Yokohama tires but on the Saturn sizes, they like $30 a tire more than the Falken Azensis. It may be worth trying a set once to see if they wear longer but if its only going to last a singe race, its too expensive for us.

Look, we get it and it's something Jay and I have been talking about a lot lately.

As far as we can tell, the program of the "other smaller series" is an avenue neither Lemons nor Yokohama have any interest in undertaking. We're not going to mandate people run a certain tire from a certain supplier, full stop.

We have explored other avenues with Yokohama--who like most tire companies, don't have a direct retail arm--and we have both found suppliers unwilling to take on any version of the program. We had gotten some traction with one supplier before the pandemic, but it was a pretty drawn-out process that got absolutely TNT'd by 2020. The complication of the logistics crunch during and immediately after the pandemic seems to have turned several such companies off to the idea of additional large-scale agreements (or maybe just turning them off of Lemons).

It's possible that people on the board are better connected than we and Yokohama's motorsports division are, though. If you know a Lemons person who runs a tire warehousing/supplier that is capable of shipping tires nationwide for a series with a potential current fleet of 1000+ vehicles, feel free to put me in touch with them.

Edit to add: Not trying to be snarky with that last bit. These kinds of things happen because people have an in with someone, but I also don't want to undersell the potential scale of any Lemons supply program.
