The Tire Reviews Score is the most comprehensive tire scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tire tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

The Champiro HPY felt most at home on the dry handling, thanks to a sharp turn in and quick direction change. Sadly, that was the peak of the grip, with the dry struggling in dry and wet braking, and wet handling and aquaplaning tests. Fourth best rolling resistance, but still over 20% behind the Dunlop.

The Chinese GT Radial is the cheapest tire on test, saving you around £100 over a premium rival. As usual, the savings come at an expense - wet handling, though at around 10% off the best tire on test this is closer than budget tires have been in the past. In the dry the GT Radial was a little better, just a second off on the dry handling circuit with a sharp, sporty turn in, but still needed nearly three meters further to stop the car under dry braking.

Top 3 GT Radial Champiro HPY Reviews

Given 53% while driving a Proton Exora Premium CFE (205/55 R16) on mostly motorways for 26,560 average miles
This tire came as stock with my 1.5-tonne mid-sized front-wheel-drive MPV.
It is a great tire for general purposes. It is quiet (compared to Continental CC6), and has good handling performance in both dry and wet, but braking distance in wet could be challenging. However, even with wheel rotation (swapped front-back), the lifespan of this tire is short and it got worn out at 26.5k miles (42.5k km) with steel belts exposed.
Conclusion: The GT Radial Champiro HPY is a good tire with a balance of comfort and performance for conservative to moderate driving style, but definitely not designed tough enough for aggressive driving.

Given 76% while driving a Audi S6 (265/35 R19) on a combination of roads for 1,600 spirited miles
Got these free when i purchased an S6 5.2V10 2011 back in February 2023.

Since they were "A0/Audi Approved" thought I'd give them a go till replacing them with the usual Dunlop SP Sport Maxx.

After about 1,500km they've bedded in nicely, but seem to wear quicker than equivalent Dunlops, Michelin or Pirellis (same as when i tried them on my B8 Audi S4 Avant 3.0T; those needed changing after just 6,500 spirited km).

Wet handling is inferior to Pilot Sport or SportMaxx, and braking distances are longer (they rumble under breaking, too), but dry handling is exemplary though road noise, vibration is pronounced.

For a cheap tire they're perfectly serviceable (or for a track day) but you get what you pay for.

Given 31% while driving a Subaru Outback (225/50 R17 W) on mostly country roads for 10,000 average miles
Awfyl tire! Would never buy again!

Extremely high road noise. Good grip in dry an wet, but you need to hold hard on to the steering wheel. The car wonders in every direction. As a result, had to change 1 wheel bearing and 2 tie rods. As if the steel belt inside the tires are loose or something. I'm sire this is a production error, these tires can not be this bad! Sadly, i never went to complain.

So after 10k miles the tires are completely shot. In all aspects GT radial are very bad for normal driving and normal cars. But they deliver a good XL tire for my trailer at least.

Latest GT Radial Champiro HPY Reviews

Given 71% while driving a Mazda 3 MPS (235/40 R18 W) on a combination of roads for 20,000 spirited miles
Was surprised at the level of grip these GT Radials offered, grippy in the dry and was vert good with spirited driving. Even in the wet I experienced very little aquaplaning despite hitting some slight puddles on the highway.
It was still giving good feedback in the wet when slightly new, and decent levels of feedback towards the end of its life.
Highly recommended as a reasonable budget mid range performance tire, if it held up well on a FWD 380Nm torque car like the Mazda 3 MPS, it can definitely be a good set for most performance JDM turbo sports sedans/coupes.hatchbacks.
Just be sure to rotate them accordingly.

Given 76% while driving a Ford Focus ST (225/45 R17) on mostly town for 7,500 spirited miles
After having Continental ContiSport Contact 5s, my garage recommended these as a cheaper option (was slightly skint at the time). I was slightly reserved to begin with as I hadn't really heard of GT Radial before. BUT, I can't really fault them at all! A good all round tire and I was pleasantly surprised at their performance in the wet. I have just bought 2 more and now have a complete set of 4 and unless I win the lottery any time soon, I will be sticking with them from now on... Faultless for the price!

I have an Audi A7 which came with Goodyear OE tires & didn't want to pay the price of a full set of replacement GYs so opted for the GT Radial HPYs after recommendation from Micheldever tires in Hampshire.
The tires lasted just as long as the GYs 18,000 miles with 3-4mm left & cost me approx. 70% of the price. Grip & comfort just as good!

Given 93% while driving a Jaguar XJR (255/40 R19 W) on a combination of roads for 40,000 average miles
These tires carry a budget price but not a budget quality. I am on my second set now having forked out a fortune previously to keep to the original Pirellis. The Champiros are lasting 15 to 20 thousand miles where the Pirellis only managed 9 to 10 thousand, There is no loss in high speed performance or feel and these are quieter on the road. Superb tires.

Fitted these rubber and already scrubbing 15K mileage. Good traction during dry. Good grip during wet. Definitely will buy again.

Highly recommended.

theses tires are now on their last legs after 32k miles, I'm not a boy racer (Peugeot 5008 MPV) or an old slow coach, but these tires have been fantastic from start to finish, never had any issues with aquaplaning or loss of grip when pushing it to its limit.

Replaced Potenzas with these because of cost. Pleasantly surprised; better dry grip, better wet grip, quieter. All round a better tire at half the price. Not able to comment on wear yet

The wet and dry grip are as per ratings..too early to judge the wear..it should be the same as nexen 8000..the amount of comfortness is none of my expectation..the only problem with this tire is that i had to claimed 3 newly bought tires cuz it was uneven when it was made..the car shaken pretty bad at 100kmh and above..after changing it and heaps amount of balancing work done, the car is okay now although i can still feel the shaking but not as much as before..buy again? Pretty much a subjective decision..i would if the tires are well made from the factory..
