Daily Driving on real 200 tread wear tires
 

Who daily drives on there track tires? I am planning on picking up some 17x8s and getting RS4's or Vr1 tires for track days. When I had a miata I drove to the track a few hours away on my track tires and rims. With the 86 I am thinking I should swap tires at the track each day.

How many people daily drive on tires like RS4s or other true 200 treadwear tires? How much performance/heat cycles do you lose doing this?

The car was at its peak when I was driving on the Falken Azenis RT 615-K+ tires. 225/35/R17. There was not a single downside, turn in was much better, grip of course was great, no wheel slip under fast shifting from high RPM.

I would imagine that the downside is that daily driving gives you more potential places to slam pot holes and cause broken cords/belts. Other than that, I think only your usage and mileage can determine how much tire use you'll lose from daily driving on your track tires. I had 18,000 miles on my Azenis with a few autocross events, the edges were getting smooth but they still drove and performed fine. Probably could've gotten another 10k out of them. Tire pressure has as much to do with this as anything else

I really think it's more tire dependent than TW. I'm on RT615K+ right now and selected them after doing a lot of reading on the chumpcar and lemons forums and seeing people getting good wear out of them without cycling out too easily. The older non-plus version seemed to have a bad wrap though because they would overheat real easy. In the past I ran a bunch of sets of the various generations of the Dunlop Z1, Z1 SS, ZII, ect ect and also liked them because they seemed to grip until the day they were on cords. I don't track my cars very often but go through phases where I autox regularly but if I was seriously committed to autox or track days I would for sure just get a dedicated set of tires for the track.

I had RS4s. It's great for grip and all. For me it sucked though, I'd prefer to not daily my track tires and preserve the grip for when I'm racing. Also, wet driving isn't as fun. If it were me I'd probably just do a separate set of wheels for track only and continental DWS06 all seasons and call it a day.

I had a set of Falken 615k+ that heat cycled a little early that might have been caused by leaving them on the car all summer (I'm a teacher and I wasn't really driving anywhere but it's Texas and it gets hot).

If I'm driving less than 400mi between trackdays I often don't bother changing my RS4's or Falken 615k+. I don't do the same with my RE71r's, I'll leave those on if I'm driving 150-200mi between events but even then I try not to.

I wouldn't call 200 a track tyre, summer performance tyre for the street, yes, and you can track with them, but there are much better options out there.

Alot of manufacturers have tyres with a semi-slick tyre tread, but not the soft compound. 120 and down.

Don't run real semi'slicks on the street though, the need heat and won't last long.

I'm currently running Hankook RS4 which are a good compromise, Potenza are aldo a good compromise, and both are cheap to replace.

Dunlop DZ03G on the other hand are real semi-slicks which I have used and are brilliant, but, they need heat.

The difference on track between a 200 and 100 tyre is night and day.

But a 100 tyre on the street is rubbish when its cold.

Swapping at the track seems like the way to go just curious to see what everyone is doing. First part of the season in Ohio gets very raining so the 200 tread range tires help a lot with that, my local track is Mid Ohio very tricky in the rain. I would like to try RC1s maybe after I burn through the set I get for the first part of the year.

Except for the handful of 200TW tires that are faster than any 100TW r-comp... ;)

Maxspeed, last track day I drove 250 each way from home to track. Personally I am planning not to swap tires (Falken 615k+) any longer, did it in the past, seems not worth it
As 86 MLR says, it is a 200 tire, not a sticky race compound.
Just in case, I am traveling with 2 spares, both spares can “complete” the track week end.

Ack

Your times, and your pocket will agree that swapping your 200's for some soft R comps when required is the best option.

Plus you can keep the tyre weight down as a smaller R comp will out perform a larger "200 street tyre".

A few years ago I won a set of R comp tyres for some event, the tyres available were 235, I put them on a set of R34 GTT rims, 17 x 7.5, first session out I PB'd.

IIRC the tyres that were on the car usually were 265 Z1 star specs, (cheap as chips through tirerack, expensive as hell here), good tyre that held up well to the 1500kg, but really only a street/khana tyre.

Point of note is the R comps I won were old stock, a few years old, and they absolutely smoked the new Z1's.

Which ones are they, what conditions do they like and what sizes?

If I could find a 200 that out performs a 100 I would seriously look at them to replace my current RS4's which are at 50%.

bfgoodrich sport comp2 gets my vote. thats a ton of tire for the price

340? I must be looking at the wrong tyre

Tirerack doesn't really rate them well

I am happy to be schooled IRT this

I dailyed, tracked, and autocrossed Z2SS in 2015 iirc and would do it again. They lasted about a year and I should have junked them at ~15k miles (they only saw 3 track events, maybe 8 autoxes and I was not pushing them to their limit) but stretched them to 19k and they were showing cords.

imho it depends on alignment and how frequently you track, I think I was at about -3° camber up front with the Z2S at the end, if I was going much past that I'd think twice about dailying them, but if you do enough track time the daily miles won't be a blip on the scale for how they wear. Right now I'm DD-ing Firestones because I'm not bothering to change alignment between autox events at -4°-ish of camber so having the ~340TW cheapo tire take a beating is fine.

As for livability, it's fine imho, yes louder, yes lower fuel economy, I drive to the event with my RE71R's on, still good for ~130-150 autox runs and a few thousand street miles. Try it out, you won't kill RS4's or VR1's by putting a few hundred street miles on them (as long as your alignment isn't terrible). For me if I wasn't going to the track more than once a month, swap 'em out and save 'em. Swapping tires back and forth 1x per month isn't too much trouble for me but I got tired of doing it at 7am after driving for an hour or two to an event.

Try it all out, drive their on your street tires, track tires in the trunk, swap, drive home on the track tires, change 'em back to the street tires when you feel like it.

Edit: @86MLR Bridgestone RE71R and BFGoodrich Rival S 1.5 are assumed by most people stateside to be faster over a single lap than any other 200TW tire, they're designed for autocross and 40s-60s runs not sustained lapping like the RS4, Z3, etc. I've never tracked the Bridgestones but from what I've heard they overheat pretty quick and you spend your session managing heat in the tire. The BFG's are likely the same.
