![]() ![]() The reason I hadn’t previously tested the 651s on a Miata is because Accelera only made them in a 195 width. You can read that report over here, but the gist of it is that the 651s were fast in a straight line, but lacked cornering grip compared to the N Fera Sur4G. That car is brutal on front tires, and we destroyed them quickly I didn’t feel it was a fair test of this tire. I’ve raced on the 651 Sport previously, but in a Honda minivan, in a 24 Hours of Lemons race. The tread pattern also has three center grooves, which is something you see on 300 TW tires and not 200. Most of the people using this tire are drifting, and even though the treadwear carries a 200 UTQG rating, this is a mid-300 TW tire, grip wise. ![]() I recently tested the Accelera 651 Sport, and I’m not shy about sharing this data, because it’s not a competition tire. Or at least it’s not something that’s shared with other people without some means of compensation. I don’t know of anyone else who has such an extensive database of tire grip, but then I wouldn’t expect to! It takes a lot of time, money, and effort to gather and collate this data, so this is the kind of thing one keeps to themselves. I often put one of my Aim Solos in other people’s cars, and the list of tires that I have data for, but didn’t personally drive, is about twice that many. I’m sure I’m forgetting some, but you get the idea. Tires that I have personally tested and have the lateral G data for are the following: Achilles ATR Sport 2, BFG Rival 1.5 S, Bridgestone RE71R, Champiro SX2, Continental ECS, Douglas all-season, Dunlop DZ102, Falken 615K+ and RT660, Hankook RS4 and Z214, Hoosier A7, R7, and SM7, Maxxis RC1 and VR1, Nexen N’Fera Sur4G, Nitto NT01, Pirelli PZero PZ4, Toyo RR, and Yokohama S.Drive. This removes the peaks and valleys from the 10hz GPS data, and also idiosyncrasies of driving style and line, and gives me a solid number I can use to compare to other tires. I export the data to a CSV file, and then average the lateral Gs through 200 feet of that corner. The primary way I evaluate tires is to look at the lateral Gs in Turn 2 at Pineview Run, a long right hander. Some of that ranking comes from online tire reviews, but a lot comes from my personal testing. I wrote the rules for the Pineview Challenge Cup, and I rank every tire individually. Tire testing is a hobby, but also something of a responsibility. And then I’ll stumble across cheap take-off slicks that are priced so well that I don’t have a choice. Some of this is bargain hunting: I got Yokohama S.Drives on closeout and was out the door for $200 mounted and balanced I bought 225 Maxxis RC1s on closeout for $108 each, with free shipping I’ve bought Douglas all-season tires for $36 for sliding around and training. This is my favorite tire and I see no reason to do HPDEs or endurance race on anything else.Īnd yet… I keep buying different tires! Some of this is wanderlust, to just see what else is out there. The 245 is good for tight courses and for more powerful cars on 9-10″ wheels. The 225 is an ideal choice for most upgraded Miatas on 8-9″ wheels. The 195 is really a 205 width, and a good choice for Miatas on stock power and skinny wheels. It’s not the fastest, but it’s fast enough, decent in the rain, has great feedback, lasts forever, and is available in three 15” Miata sizes. If I was going to pick one tire to use for everything, I’d use the Hankook RS4. ![]()
