Tires SUMITOMO or RIKEN

I have been using the Sumitomo HTR A/S P02s for the last 80k (just go 3rd set on front) as a good compromise in price and quality.

I had a good experience with Sumitomo htr a/s p02.

Speaking of cheap tires, I recently switched my tired old 41k mile Sumitomo ZIII with these $43 in 225/45 17 Riken raptor ZR and quite surprised how well they are. They grip as good as my ZIII did, way quieter and rain performance was fantastic. I was hesitant at first until I read reviews on tirerack phrasing these are great tires and they are definitely good. I also learned Riken is part of the Michelin tires company so its probably of decent build quality.

running 40psi, when i go to the track, i keep it at about 38 and check and let out hot air as i go each lap, ill go from 35 to 50*f after a few laps so i always am messing with air. 205/40ZR-17 SUMITOMO HTR Z II 17x8 Axis OG Europa SDC

I got some $50 Sumitomos on Tirerack for my current beater because I couldn't be bothered to spend more money on this car. Nevertheless, they have not failed me in the wet, snow or sleet.

They have an aggressive tread pattern and I have driven them for the last 7 months in a variety of conditions from downpouring rain to hot, humid sun and they have not let me down yet. I push them hard on a cloverleaf on-ramps. They grip well and don't even chirp.

I have them on my 86. The sidewalls are OK, not great. They do leave something to be desired as far as cornering, as they seem to break loose with little warning.

I had the HTR+ a few years back...wouldn't recommend it for someone who is looking for a reliable track tire or a super performance tire...but I was quite surprised how well it did for everyday driving and the occasional spirited lapse in judgement...LOL...price was very nice too

they are actually very poor tires. the sidewall is super soft an the compound is far from ideal. i ran these in maybe two autox's an they were just plain sad.
