R COMPOUND TIRES. these are the race spec tires that people will run for competition purposes or zealous street use. they range from the mild all purpose ra1 to the wild full slick hoosiers that are a joke when it comes to being approved by dot. r comps are dynamic, they will harden with heat cycles. this means if driven on the street daily they will get hard and take longer to heat up and also possibly last longer. i will not talk too much about turn in characteristics as most r comps have great sidewall stiffness. this means that they're a bit ruffer on the road but also if you get wider tires you get more trampoline effect and it's less harsh so it's a good trade. r comps are also more dependant on operating temp, so be careful on cold tires.

TOYO PROXES RA1 is the most common r compound tire found. for the performance it's a steal. light off characteristics are good, usually less than 1 lap of a 1:30 track when they're full tread. this is the track monkey tire. this is also the zealous street user tire. did i mention they're cheap? the ra1 is the the standard when it comes to rcompound tires. as with many rcomps the ra1 comes with shallow tread and has a significant amount of rubber left after the tread blocks are gone. these tires are thus best shaved and will fair bad weather if you're super slow (however in slick form they should see only dry pavement use). they also retain street tire like noise when breaking away which makes them very "forgiving". these are SYMETRIC and can be flipped. these tires last long when it comes to track days and they're unshaved.

NITTO NT01. these tires are similar to the toyo trampio 888. fast, soft, sticky. they will not last as long as ra1s, but (since nitto is the same company as toyo) this is toyo's newest offering to bridge the gap between ra1 track monkey tires and the hoosier class rubber and are seconds faster than ra1s on a typical. tho these tires just came out there can still be much info inferred as these are directly comparable to the toyo trampio 888s. the tread patter on these guys is sick, huge outter contact patches. early testing of these tires turned up lackluster, but the tire has been very well accepted by the community which may suggest that tire shaving could be crucial for this tire. the nt01 is also more heat forgiving and will work in a wider band of heat than most other r compound tires. definitely ASYMETRIC.

MICHELIN PILOT SPORT CUP. these tires have mixed reviews but most likely because they need to operate very hot before maximum performance comes on. and after that fact they wear very well. these tires are favored by many porsche racers and will out grip just about all other treaded r compounds. ASYMETRIC tire can't be flipped.

YOKOHAMA ADVAN AO48, this is the replacement r comp from advan, i will not talk about the ao32 as it is discontinued. like all advans these are expensive. they come in varying degrees of hardness and for heavy cars like the evo you want the harder compounds. they will also not last very long and are not good for many seconds over ra1s however these new ones may pose a change. SYMETRIC can be flipped.

KHUMO VICTORACER V700. these tires come with wee itty bitty tread depth. these tires will outperform ra1s in some aspects but the ra1 is generally more favored due to availability, standing the test of time with success and the fact that they last longer. that said the victoracer v700 will not last as long as the ra1 with street driving. ASYMETRIC not flippable. more info to come. khumo recommends tire shaving for all dry competition track use.

KHUMO ECSTA V700. these tires are great for autocross but not the best, more like an autocross practice tire. comes with itty bitty tread depth and will shave in quickly to slick. at autocross these tires will last many events. keep in mind that these do not compare to the victoracer v700 and are definitely not comparable in any way to the v710. khumo recommends tire shaving for all dry competition track use.

PIRELLI PZERO CORSA. tread pattern is worthless. warm up time is longer than that of an ra1 and it matters! these tires will not hook up well when cold but once warm they will dish out the status quo in terms of grip. these tires are also faily silent, they do not make very much noise when breaking away. these guys are ASYMETRIC and can't be flipped. i need info on how long these last at track days

HANKOOK VENTUS Z211. total time attack tire. wears way too fast and takes a dump after more than two handfuls of heat cycles. but they're a lot faster than ra1s. they should basically be compared to a hoosier as they are about 1.5 seconds faster than ra1s. these are available in hard and soft compound. these tires are wider than most similar size description tires. ASYMETRIC

KHUMO ECSTA V710. autrocross and track tire, hoosier style 'slick' (two worthless thread lines). these tires whoop ass bascially and compete with hoosiers in autocross. at autocross people will tell you that these tires take all the heat and don't bat an eye, however i've still seen evo owners busting out the water sprayers between runs. when it's time for the ultimate performance at autocross this tire is run by everyone that is doing worthwhile times. ASYMETRIC. khumo recommends tire shaving for all dry competition track use.

HANKOOK VENTUS Z214 this is a v710 like tire. and like the v710 it is a track only tire, two SYMETRIC lines for tread patter and steel belts. this is the slick type tire that was used by the xsengineering skyline for the american touge. this tire is likely the fastest tire in its class (belted tire with almost zero thread blocking), that said it doesn't last long and hardly anyone uses it. i regretfully cannot comment on the heat characteristics at this time. but thers is a c70 autocross specific compound.

HOOSIER these are race tires. they will heat cycle out before dangerous wear shows and that said they'll wear quick too. hoosiers are notorious for being sensitive to heating and wearing, you gotta drive them right, smart, but when not asshatted all over the place there are few tires, sans slicks, that reward so directly. hoosiers have been known to wear on the shoulder, but new A6 and R6 tires have addressed that, how successfully is still yet to be determined.

HOOSIER A6 this is the dot approved autocross tire, basically they have steel belts. since these are relatively new, little information is available. however basing off of the previous hoosier a-tire running them on a heavy evo may require attention to heat management.

HOOSIER R6 this is the dot approved roadrace tire, basically they have steel belts.

if you pay attention i've ordered all the tires in a 'most popular' or most likely to be picked kinda way, some of the most competitive tires won't be considered by many hence the hoosers and khumos roaring up the rear where the ra1s are very common for rcomps as they can be run on the street.

I will not be discussing slick tires as most people running slicks will not need this guide, that said most slicks are harder to find. just about every tire manufacturer makes slicks. yokohama, goodyear, michelin, hankook, dunlop, pirelli and bridgestone all make slicks. slicks are generally about 3 seconds faster than the fastest dot approved r compound tire of a similar size. slicks are very heat sensitive and very unforgiving to things such as tire lock up and too much slip angle. being a slick design the tire can shear easily and the wet performance is non existent. with that stated one can likely cheat by running a weather slick (a slick with thread pattern) and get most of the compound benefits while running in the dry. also slicks are weight sensitive as many of them are designed with a stripped race car in mind, so overheating is a problem which will increase the wear rate and the cycle life of the tire drastically.
