Riken UHP Owner Reviews

Review this tire

What owners say summarised from 16 reviews

Owners of the Riken Riken UHP generally like its dry grip, value and comfort, while wet-grip praise also outnumbers criticism. Wet confidence is not consistent, however, with reservations from around one in five reviews and a few accounts of limited cornering performance. Two drivers report sidewall damage after pothole impacts, a minority experience rather than proof of a general failure rate. Nine of sixteen reviews describe the tire when new, so the overall picture leans towards early impressions. Later-use mileage accounts offer some encouragement, but one driver reports less wet stability near the wear limit and there are no repeat reviewers to establish an ageing pattern.

Initial Impressions

These came freshly fitted to the car when purchased - I guess they were the cheapest tires to get it mot'd. To summarise they were just OK in all respects, though ultimately lacking for any spirited driving - especially in the wet. Decent comfort. Biggest frustration for me was inadequate rim protection - the slightest curb encounter resulted in scuffed rims. Replaced with Goodyear Eagle F1s - no comparison really.

Initial Impressions
Despite the unusual first-season slipperiness, the Riken UHP develops into a reliable and capable tire. I was satisfied with its performance, and in terms of price-to-value, it’s absolutely worth it.

Those tires were on the car when I bought it. There is some tread left, but I decided to get all seasons (Michelin CC3). They are good on dry road, but I cant trust them on wet...

When I purchased my Lexus GS450H it came with rear only Riken UHPs and in the dry with roughly 4mm remaining tread very grippy hard to destabilise the car without turning off TCS.
Performed well in wet conditions with essential tread levels BUT, be careful on wet conditions and especially when at legal limit tread levels the car can destabilise without too much effort. Otherwise quite solid.

I got around 6000 miles from around 4mm when I got the car so 12000 miles estimated when new.

The tires have a very soft sidewall, even with my low 40 profile tire, this meant that they are comfterable and pretty good in the dry and wet. I had only had budgets or random tires on my car before these and so when I went on a country road drive the front end felt much better (well duuhh). For the money these have decent performance but there is a major downside to these tires... If you hit a pothole these tires will just go, I went through both of my fronts in about 2 months doing a lot of town driving. For this reason I dont' recommend these tires if you live in an area with bad road (ie the entire of the UK)

Purchased these tires 2 months ago as replacement for hankook Ventus. I’ve tried my best to push them to let go in wet and dry conditions and have never lost grip enough to feel in any way out of complete control. Sport mode with driver aids disabled can barely elicit wheelspin before the grip asserts itself and launches the car very satisfactorily. Quiet comfortable ride. Best value tires I’ve had in years £250 fully fitted on four corners with nitrogen inflation. Will definitely be buying again in future. Premium tire performance at budget tire price. Get some on your motor and rag them if you can or dare to. Because despite my best efforts I cannot find any real fault. Can’t speak for long term wear but they still look off the rack pristine after 1000+ miles.

Brought these for me rear wheels and I really think they are brilliant. I have now done 9k miles and still have about 4.5mm tread. I have driven on dry and torrential weather and have never spun, this is a really underrated tire and I will be buying again.

Tire is great in wet or dry and comfortable BUT they have a very weak side wall. I have replaced 2 inside 1000 miles due to side wall damage hitting a pothole and now a 3rd has a bulge after 600 miles. I will not buy them again for British roads
