Hankook Ventus iON S 295/30 R21 Tesla Plaid 1,000 miles December 3, 2024
Michelin that were delivered with the car wore out after approx 20.000 km. I mostly drive on Autobahn and using the Plaid model for that reason as model 3 throttles from 200 km/h. ABS kicks in on all 3 Teslas that I've tested, when driving a bit fast in curves, which seems to create uneven tire tread wear. Hankook ion seems to be better in this is respect than Michelin and Hankook Ventus s1 evo3. And ion also produces less noise than my old Michelin tires. So far ion seems like the better tires for Teslas...

Accelera Iota 295/30 R21 Volkswagen Toureg R Line V8 Diesel 5,000 miles September 26, 2014
Absolutely ATROCIOUS! Put a set of 295's VW Torueg R-Line as we could not get ANY other tyre for it (ridiculous rim / tyre size by VW...... again).

These Accelera tyres vibrate the living daylights out of the steering wheel, our hands literally tingle after ten minutes of driving, they pull to the left even after three x four wheel alignments and its like driving on cobble stones all the time only you are actually on a smooth highway!.

Multiple wheel and tyre balances and the tyre guy actually apologised that the tyres were basically "such crap"! His words! He's now trying to find us another tyre..... In a 21" rim..... Stupid size that virtually no-one makes a tyre for!

Never again for Accelera or a VW!
