Top 3 Accelera Iota ST68 Reviews

Accelera Iota R20 Iota-1 & Iota- st68
The Iota have 2 different types of tread the Iota-1 and the Iota- st68. made by EPtires in Indonesia (not china)
I bought a Q5 sline+ with the chunker Iota-1 on it and was surprised at how good & quiet they were for a non premium tire. No issues with steering, ride and grip. Also they looked good on the car. Only slight negative was fuel economy witch you’d expect with the chunky tread. Unfortunately this vehicle was written off after a stolen car rammed into the side of it at 65mph. I went and brought another Q5 sline+ as I consider this car saved mine & my family’s life.
This one had Michelin lattitudes on it 4-5mm tread. I immediately felt the difference the car felt more prone to movement and absolutely hated white lines causing the car to skate. Ride was pretty good and I know the grip was there but I just wasn’t as confident driving on these tires. I didn’t like them. I have recently changed the tires to Iota- st68. Thought id give them ago as I couldn’t easily find the Iota-1. They also have a more normal summer tread for fuel eco. And are amazing cheap compared to the £250 premium per corner.
The Iota- st68 have massively improved the driving on normal roads, no skating on white lines or veering, grip seems good. No real under/over steer. However this is at ride cost. I found this really not much of an issue on normal roads & quite like the feel of the road, but on the motorway there is more shaking on bad road surfaces. The Iota- st68 are defiantly much stiffer on the side wall, maybe this may soften slightly in time to give a better motorway ride. Indecently the rubber on the tires feels fairly soft & they had a 68db sticker on them and they are quiet to go with that, another reason for buying. Both Iota treads have all season written on them however, looking at the tread pattern I doubt the st68 actually are. The Iota-1 may offer more winter traction. I drove these on wet grass a few times no issues. The ST-68 Braking doesn’t seem as good as the Michelins but maybe that’s expected also im possibly driving faster with more confidence now. There’s also the new tire breaking in factor where you need to get rid of the mould lubricant. Both my sline Q5 had standard suspension (Code 1BA) rather than sports (1BE) I would suggest the Iota- st68 are too stiff for sports suspension considering I have standard and if you do a lot of motorway driving I would necessarily recommend them at the moment however fuel eco is very good.
All in all for the price the Iota is very good in either pattern depending on requirements. If you want premium then I wouldn’t recommend the old Michelins, but they have just brought out the Lats 3 which don’t have a smooth centre tread so may overcome the issues of its predecessor. I hear Bridgestone’s are too hard, but good year eff-grip are somewhere in the middle so these maybe the best all-round suited Q5 tire and the’re OEM as well. Hope this has been some help but realise it may be no help at all!!

After a 1600km motorway trip these tires have fared very well so far. The terrain consisted of dry, wet and ice and at no time did I feel like I was losing control of the car. They are very quiet and comfortable and mine are 22s. Early days but so far so good.

Given 87% while driving a Vauxhall Antara (225/45 R17) on a combination of roads for 8,000 average miles
Running my Vauxhall antara on a full set of st68. Covered 8000 miles .still plenty of tread left. For a budget tire I have found them better than most. I am not a boy racer but I don't drive sedately either. I live in a town full of roundabouts and so front nearside outer edge of tire takes the brunt of the wear. Very pleased all. Will purchase same again. I have driven in all weathers, including snow. I didn't crash or get stuck so they can't be that bad. I do wonder how some people drive when you read some of the reviews.

Good road holding in the dry, much better than the scary pirelli scorpion in the wet condition, doesn’t aqua planned as much as the pirelli scorpion that came with the car. Have only driven for 10,000km so let’s see how long it would last, i’d be happy if it last 40,000km but the compound seems way softer compare to the scary pirelli scorpion.

The Accelera IOTA ST-68 replace my original ones from factory Continental ContiSportContact 5 lasted 25000 miles & 3 and half years, good tire but a bit noisy and £40 a corner more expensive. I only done 1000 miles and so far, makes the car drive smother and quieter rated A-68db C+C 103 V XL. I will come back later after I done a bit more mileage, these Accelera IOTA ST-68 have a new pattern. I already driven in heavy rain and their stud very well I was impressed, so far 4 stars

Given 84% while driving a Land Rover Range Rover Vogue SDV6 (275/40 R22) on mostly motorways for 20,000 spirited miles
Positively surprised by the overall performance of these Tires. Budget priced but quiet and cannot fault the grip in the dry and especially in the wet which is where I thought they would be susceptible. Fitted to a Range Rover they have now done over 20,000 miles and still have a good few thousand miles left in them. I had just bought the Car and after considerable expense in the initial Car purchase put these Tires on with the intention of upgrading them to a set of the well known brands later on when finances permitted. I honestly can't fault them and shocked at how well they are performing to the extent that I will be replacing them with the same when they eventually wear out. I drive around 25K miles a year and have done for over 40 years and these tires are as good as any I have experienced in fact even better than some of the more popular German, Italian and French brands which are literally double the price and then some. In the past I have bought some budget tires and instantly regretted it realising it was a false economy but these Accelera ST's have totally surpassed my expectations.

Given 84% while driving a Audi Q5 (255/45 R20) on mostly country roads for 20,000 average miles
In October 2019 I needed to change all 4 tires on my Audi Q5. I took into consideration that I was going to be driving on a long holiday to Italy in June 2020, so I did some research and tried to get the best set of low cost tires to last me until June when I would change to more premium ones. Well Covid 19, appeared my holiday was cancelled and it’s now January 2022, some 2 years and 4 months later. I never did buy those premium tires. I still have some tread on all the Accelera Iota st68 tires but because an idiot driving at speed two months ago forced me to hit a kerb at about 25mph I badly damaged the edge of one tire and two have inner wear. I only noticed when I recently washed my car. I have decided to change all 4 and guess what I’ve bought another set of Accelera Iota ST68. 4 tires plus fitting and disposal of the old ones has cost me £441 that’s £110 pound a corner. I’ve done over 20000 miles on the old ones so I cannot complain and I have no complaints.

Given 88% while driving a Land Rover Range Rover Sport (225/45 R17) on mostly town for 1,000 average miles
Fitted IOTA ST68 275/40 R20 to the front of my 2012 Range Rover Sport replacing Pirellis. These are a revelation, in terms of road holding, comfort and general improvement to the handling of the car. The car is now a pleasure to drive and is almost unrecognisable from the experience on Pirellis. I tow a caravan and have just returned from an 700 mile round trip. The previous tires had a disconcerting habit of following the ruts made by HGVs in the inside lane to the point, at times, it was almost dangerous. I can't even say I noticed this phenomena with the Accelera tires. I can't comment on longevity but at about half the price of top branded tires I wont be too concerned. Very pleased will definitely buy these again.
