previous tyre toyo proxes r50. recommended pressure 210 front 200 rear. i pumped 230 front 220 rear because pumped lower felt underinflated and more wear on the sides, pumped higher felt harsh.
changed to UC7 and driven 600km to date. my review;
- pumped 220 front 210 rear to get the sweet spot.
- a bit louder than the toyo.
- slower acceleration at the traffic lights compared to the toyo
- dry grip, i feel toyo better
- cant comment on the wet grip yet since no rain until only yesterday
- the road surface dampening, UC7 much better than toyo. rough road surface and small holes, i felt like deep thud. not harsh bang.
- at 220 kpa, the sidewall didn't bulge under the car weight as much as the toyo at 230 kpa.
- fuel consumption on uc7 is higher maybe due to nore effort to accelerate. Fuel level drops faster than before on the same driving routes
i guess the less bulge due to the stronger sidewall. the slower acceleration maybe due to heavier weight of UC7. the UC7 is rated for Extra Load
May I ask how is the UC7 on your car holding up? I went to tyre shop yesterday looking for UC7 and the boss is still checking on the size for me. There are some UC6 at the shop but the UC7 is said to be a clear improvement to the older UC6 particularly in terms of noise. It is said to be quieter. The UC7 is said to be a good all-rounder with decent or good handling in both wet and dry, and also good comfort and quietness. Sounds good to me. The Goodyear Assurance Triplemax 2 currently on my car is rather noisy now and the tread of the tyre looks a bit worn although it's only 2 to 3 years of usage, probably about 20,000km to 25,000km only.
