Q7 Tyre Review

[Gavin0478]

Well today I have refitted my summer wheels as it looks like the bad stuff is just about over.

As my Michelin Latitude sports were fairly well worn (few mm left so on eBay haha) I wanted to start the summer with new rubber.

After much research looking at hardness, wet grip, efficiency & noise I settled on some Altenzo Sports Navigators which for a set of four 295/35/21's came in at £460 delivered (+£40 for fitting).

My choice was because the noise, efficiency and wet grip are rated the same as the more expensive tires so not in the same leagues as budget tires and also that the hardness of the tire is rated at 440 which is harder than the Michelin tires that I have taken off and for the price if they prove to be less than expected I wont lose much by flogging them and sticking some other rubber on.

These were not the cheapest at the moment but not much more expensive than the cheapest budgets which on the face is good value.

The quality looks good as these are an Australian designed tire, they are also not directional tires so fitting is easier.

They fitted and seated easily, balanced up well too so no problems there.

I only did a handful of miles on them today but the turn in feels good and they are quiet too.

The specs are tread wear and traction A, hardness is 440, economy was C, wet grip is B and the noise is only 72db.

Once i have tried them out for a few miles in all weathers I can update both the grip and how the wear is looking.

I hope this may help people with tire munching Q7's

You might want to consider UniRoyal Rainsport 3?

I would go for Goodyear Eagle F1. More expensive but I had good experience on my previous A6.

You might need to check for sizing though :)

Do you mean US Treadwear Rating? that can only be compared within the brand
UTQG Treadwear Grades are based on actual road use in which the test tire is run in a vehicle convoy along with standardized Course Monitoring Tires. The vehicle repeatedly runs a prescribed 400-mile test loop in West Texas for a total of 7,200 miles. The vehicle can have its alignment set, air pressure checked and tires rotated every 800 miles. The test tire's and the Monitoring Tire's wear are measured during and at the conclusion of the test. The tire manufacturers then assign a Treadwear Grade based on the observed wear rates. The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.

The problem with UTQG Treadwear Grades is that they are open to some interpretation on the part of the tire manufacturer because they are assigned after the tire has only experienced a little treadwear as it runs the 7,200 miles. This means that the tire manufacturers need to extrapolate their raw wear data when they are assigning Treadwear Grades, and that their grades can to some extent reflect how conservative or optimistic their marketing department is. Typically, comparing the Treadwear Grades of tire lines within a single brand is somewhat helpful, while attempting to compare the grades between different brands is not as helpful.

Wow.. highly technical post. Great one sir.

That's why I eye each ratings on the tyres pretty suspiciously.

I too have the 295 35 21 wheel and must say that I am very pleased with the wear and life so far out of a set of nangkang as-1 's I fitted last year. I love the built in rim protection and the way the outer wall tapers in, I'm no expert but I think this is helping with wear on the edges on the front on roundabouts, was hesitant as what to do tyre wise last time but come to the conclusion I've tried Pirelli r01 and they don't last, tried Yokohama and they sit too square on the rim and wear on edges way too quick so I might as well try budgets and have to say very impressed would buy again. Plus the were only £116 each from love tyres.
