The Tyre Reviews Score is the most comprehensive tyre 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 tyre 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.

What the Toyo 350 lacks in comfort, it makes up for with excellent steering response and feel. A great tyre in both the wet and dry this is the tyre we'd pick for a fun B-Road blast. Wore slightly better than the Conti too.
The Toyo is mostly let down by it's comfort and noise.

Top 3 Toyo 350 Reviews

Given 48% while driving a MG Midget Mk3 (155/80 R13 T) on mostly country roads for 3,000 spirited miles
theses are not bad tyres but just not suited to a small 1960/70s British sportscar like the MG Midget I have

I've had different models of Toyo tyres over many years so I know they can be very good as a make

the 350 seems to me to have a very upright sidewall which gives a harder ride in a small lightweight (very lightweight by modern standards) sportscar, I had to reduce the running tyre pressure (from the previous tyres) to prevent the ride being too hard

the handling in the dry is that they allow plenty of side movement but a bit too much too soon for my liking and take up too much of the roads when driving in a spirited manor - in the wet they're not as good as in the dry

they do have a progressive feel to them and do communicate what they're doing but their limits are far too easily reached for spirited driving of a lightweight sportscar

braking in the dry I've found to be good and progressive but I've not tried the heavy braking in the wet, I suspect they'd come good in the end but give you a worry before getting there

on another vehicle these could perhaps be more than reasonable tyres but I repeat again not on a small lightweight 1960/70s British sportscar like the MG Midget

Given 75% while driving a Ford Laser KH2 1994 1.8L Manual (225/45 R17) on a combination of roads for 1,000 spirited miles
The first thing I noticed when I got these tyres, was how much lighter the steering was.

My previous tyres were Diamondbacks, typical $49 bargain bin junk, I drove the car 500KM before putting them on the rear and getting new tyres for the front.

The vehicle I drive is a 1994 Ford Laser.

Grip: Dry grip is much better, with the diamondbacks in first gear there was more torque steer, and more likelyhood of getting wheelspin.
With the Toyo's it's definitely more of a challenge to get the wheels to spin.

Progressiveness: I haven't used them long enough to judge, I have experienced understeer, but only in full throttle while cornering situations.

Wet grip: In the wet they are brilliant, after changing from the diamondbacks I was convinced my car was down on power, but it just feels slower due to the better ride and increased grip.

Buy again: I'm not sure if I would, only because I'm yet to try other brands, I like the tyre, and I probably would choose it again, but curiosity means I'll try a different brand next time.

Road noise seems very low at 100-110KM/H.

Given 83% while driving a Honda Civic (175/65 R14 T) on mostly motorways for 9,000 average miles
I'd definitely buy these again. At 90 a pair fitted they are excellent value. Like most people on a commute I don't drive like an idiot but I've never had any scary moments in wet or dry. They're quiet on the motorway but the best feature for me is the wear rate. I've covered about 9k so far with these on the front of a civic 1.4 and they're still showing 6.5mm. Can't fault them.

Given 94% while driving a Toyota Yaris (225/45 R17) on mostly country roads for 10,000 average miles
Excellent mid range tyre. I've had it a year and think I will get a couple more years out of them perhaps 30k miles.

Given 84% while driving a Ford Mondeo (185/65 R14 T) on a combination of roads for 300 average miles
Bought these to replace Pirelli P3000s, noticed a distinct improvement in grip - especially in the wet. Overall very happy with these - good performance at a budget price. I'll certainly be buying Toyos in future.
