Accelera Iota ST68 Owner Reviews

Review this tire

What owners say summarised from 24 reviews

Owners of the Accelera Iota ST68 most often praise its dry grip and low purchase price, with favorable wet-grip reports too. Ride comfort also attracts more praise than criticism, although opinions on road noise are divided. The main concern is vibration at motorway speeds, raised by around a third of owners, sometimes persisting after repeated balancing. Tread life varies: several mid-life and end-of-life accounts describe useful mileage, while others report early replacement or rapid wear. The balance of feedback is positive, but the vibration reports are substantial enough to weigh against the price advantage.

Terrible tires that vibrated had them rebalanced 4 times. Conclusion by tire fitters was they were out of round. Garage that supplied them brand new with the car didn’t want to know and Accelera wanted proof of purchase from the garage who wouldn’t provide it. Ended up swapping them for Michelins which were like heaven transformed the car. Would never touch Accelerra with a barge pole -poor tire and poor customer service.

On a 2022 Chevrolet Suburban. Tires gave confidence for 10,000-12,000 miles. Needed to be replaced at 15,000 miles. I had fiber showing at 18,000 miles. NOT a long lasting tire.

Traction was ok during lifetime. Not recommended for snow or ice.

I know mileage is not to be expected at this price point, but personally, I'd buy a set of used tires of a reputable brand for this price and expect them to last longer.

I fitted a set of four these on My BMW X6 30d
22 inch Wheels
Although I've given them all 10 star ratings the most important thing I've got to say is they work just fine. I don't race my car around a track where I live there's quite a bit of traffic which I generally just go with the flow. If it's raining heavily I adjust my driving accordingly again I'm not racing about. Very initially I thought the ride was a tiny bit harder but I just let a little bit of air out of each one and I can't honestly say they feel any different from the original continentals
Here is the rub.
Accelera Iota ST 68 £470 a set of four
Premium brands all around £1400 for a set of four.
Can't comment on longevity at the moment but I could have three sets of these for a set of premiums!

Very good silent and comfortable tires with pretty good grip on the first 5.000-8.000km. Started becoming very noisy after 10.000km and almost completely bald at 20.000km. Not recommended to use for heavy rain, these tires have a hobby of aquaplaning, braking distance also increase by quite a lot when using these tires. Probably one of the cheapest tires I can get for the size (second to the GT Champiros which are way worse with the body roll, no grip and very loud). Considering the price and wear of the tire, seems quite expensive, changed to the Goodyear Assurance Max SUVs which are much better in almost every aspect except the comfort level of the Iota is still unbeatable at its' price point. The goodyears are 12% more pricey but lasted more than 50.000kms turning out to be cheaper, and doesn't get louder with more wear.

As others have stated, vibrate at about 65 - 70 mph. Had them balanced twice but can't stop the vibration.

Surprised at the quality of these cheap tires. Bought other cheap tires for other cars and generally you get what you pay for but these are good but they don't last long

Quiet and comfort at slow speed, but vibrates like hell when cruising at 60 mph. Ride feels plush and quiet on my Lexus RX350. For this price, I can't complain.

We bought a Ford Edge in 2020 and it had a brand new pair of these fitted on the front. I’d never heard of the brand and I was a bit sceptical.
But 3 1/2 years later we have covered 21,000 miles and the edges are just going off, I think they have worn very well on the front of a 2.2 ton car and a good 8k of the miles had been towing a large caravan.
They have performed well in all weathers and the car has been driven quite ‘spiritedly’ at times.
I have just ordered a new set of 4, so if I can get another 3/4 years and 20+ thousand miles out of them I will be very happy.

I have had these tires on my car for 3 years,covering almost 18,000 miles. The rears are practically still new the fronts have about 3 mm left on them.
Living and driving in central Scotland we have a lot of rain, and these tires have never let me down in some challenging conditions including snow.
Just starting to feel the front not as grippy as they have been. I will be looking to replace them within the next 1000/2000 miles,i can honestly say these tires haven't let me down in Dry and Wet.
