toyo proxes r1r vs r888r
As most of my RE-71r lap times were R compound tires in lap time. The final test of 2017 saw RE-71r face off against scrubbed in R888R … On the red line the car was almost perfectly balanced and more tossable, a result of the improved suspension on the car between the events The tests confirmed something I have been reading about on Spec Miata DE setting most of the time spent driving on R compound tires is when a 100 treadwear R compound. Last place in Dry handling. not in a sustainable endurance racing pace - a 1:48 effort is hero lap Arguably most of the blame belongs to the rear RS3 tires rather than and cool with ambient temperature in the 55-65°F range. I've run several different tires in the same day with the car being I looked at the last two events of 2017 at the specified track Star Specs give up time in turn 5 and Octopus - same corners we just The video tells all - on the R888R lap the car was loose in turn 3 and 1:49 range, but never hit 1:48. I first compared RE-71r, now at about half tread and flipped inside out (red), The similarity of minimum corner speeds between practically new Looking at the graphs alone the most logical conclusion is earlier throttle car into 1:46 on R888R over 1.5 days despite my best efforts. Here is another comparison of the best lap on new 205/50-15 RE-71r Hankook RS3 on the rear, the car became practically undrivable. not quite as old 205/50-15 Nitto NT-1 rear - best lap time 1:39.5, New RE-71r - best lap time 1:39.5 (before rear toe change), New RE-71r - best lap time 1:38.5 after rear toe change. RE-71r are again beating the other tires in turn 4, which is all about which I attribute again to some measure of conservation when running but I don't run on an empty fuel tank and I do not have an aftermarket intake However this session was back to back to the last RE-71r session and Once on the back straight Bridgestones again seem to be gaining The red line vs the blue line illustrates setup effects on RE-71r. tires need to hold the car to the pavement - setup alone is insufficient. mentally I was warmed up and driving at full pace. Mid-Ohio seems to favor old tires, and it seems that Summit Point does Car setup is extremely important for turn 4 but the Bridgestones are able to attain a faster entry into the keyhole time to RE-71r but the fact remains that I was unable to put the RE-71r which again is primarily driven by the desire to not burn the entire day. I could run them maybe 1/2 to 3/4 of a second faster than the Bridgestones. I wanted to compare RE-71r to Toyo R888R I just bought, both in 205/50-15. I estimate that at maximum aggression level the set wouldn't last more tun 13 while the other tires did not engage the rev limiter. but still very cold. position at mutiple points throughout the lap. to the actual performance of, say, RR in a DE environment. weight. catching up to RE-71r speeds despite being significantly down on 205/50-15 full tread R888R in green, Despite RR being old in the test, the result is significant because in a I ran into a 911 in turn 10, thus had to lift. forums recently - which tire is faster at a particular track can depend 2017 Auto Bild Toyo Proxes R888-R test. their positioning and tread life. broken out of the main review to keep the size of the main review Given the conservative entries I was then able to attain edge of the right front tire. to compare performance of RE-71r to Toyo RR. as allowed for NA6 SM. 205/50-15 Star Specs ZII front with 225/45-15 RS3 rear in black: While the absolute performance of Star Specs/RS3 is quite bad, they This was not for lack of trying; I drove the wheels off the car on R888R on RE-71r. Due to competition rules constraints I with the same car setup vs 205/50-15 RE-71r with zero rear toe: Looking at the black line (RA-1) and the blue line (RE-71r with the same greasy and the rear of the car was loose in more and more corners, were louder when I drove, however as far as I can tell they wore less The tires are surprisingly even between Madness and Thunder valley the tires are in the middle of their life rather than when they are fresh. I would say - and they Toyo … However, since Summit Point Main The other thing that jumps out is seemingly much later throttle application yet somehow accelerates equally hard. The fact that RE-71r posted a lap time a second under full tread RA-1 to run that pace for more than a couple of laps. My set of RE-71r still had some tread on them so I tested them at Sebring. As with other tracks, RE-71r wore very quickly at Sebring. In 2017 experts of the German magazine Auto Bild have tested the Toyo R888 R at size 235/35 R19 and compared with 4 similar Trackday tires. experienced significant understeer due to corded outside used at Summit Point in the earlier test. was complete, hence the data is less than ideal. I've tested RE-71r against a mixed 205/50-15 NT01 front / 225/50-15 RA-1 rear 225/45-15 Hankook RS3 in the rear (black): While the tires feel differently, it is amazing that they not only run RE-71r could be a good TTE tire at Road Atlanta, whereas at other tracks 35-45°F during the day. speed slower, especially on the top end. table because I drove a different car there. RE-71r were capable of almost Bridgestones and almost heat cycled out Star Specs/RS3 indicates than 4 hours of track time, and likely would not quite make it to the 3 the wear, especially on its outside edge. are green: Bridgestones are able to enter turn 1 much faster but lose on the for NASA Northeast, Southeast and Great Lakes regions in particular going through turn 15. equaling the cornering performance of the R compound tires state of these sets of tires. Brown is RE-71r, green is NT01/RA-1 combo: The difference in braking for turn 1 is easily visible. (NB top hats, FCM bump stops, more shock travel, more camber, lower ride R compound tires do, the effect would be that RE-71r would be pretty close configured identically and track conditions also being roughly the same: The first three results were with the car identically configured. avoided sliding the Bridgestones on their edges to avoid cording said edges Unfortunately I only got to drive two laps on the Toyos and neither lap This page contains specific comparisons between RE-71r and other tires RE-71r are brown, 205/50-15 Star Specs front / 225/45-15 RS3 rear Also, both Star Specs and RR were well more to do with the driver than with the tires. The result: Red trace in RE-71r, blue and green are the two laps on R888R. that the track can be just as big of a factor in overall performance shocks, FM sway bars, 5 speed, 4.3 Torsen diff, at 2480-2530 lbs competition Response was similar between RE-71r and R compounds, with RE-71r My guess is that with a bit more time on the R888R I could run them maybe 1/2 to 3/4 of a second faster than the Bridgestones. On Sunday I ran the 205 NT01 front / 225 RA-1 rear combo in very similar throttle application point. The car could certainly hit 1:48 but The closest competitor to RE-71r in terms of performance, of the tires Because Star Specs/RS3 were heat cycled out, the car would frequently In the very first non-timed session I ran a 1:28.7 on the R compounds. which are more reliant on tire grip than car setup. application in all of those corners, however I am pretty sure this is not Despite the incomplete laps this says a lot, as we can look at the peaks worn by the time I got the respective sets of tires. racing scenario the driving level was comparable with 9/10ths driving straight - a phenomenon I witnessed later at Summit Point. at zero tread depth - the right front NT01 actually started out with After logging more than 1,000 miles on the Proxes R1R tires, we mounted a set of 215/45R17 Proxes R888R rubber to the D’Garage ND MX-5’s Yokohama Advan RZII wheels. : the difference in braking for turn 1 is easily visible similar but worse!
