Running my Vauxhall antara on a full set of st68. Covered 8000 miles .still plenty of tread left. For a budget tyre 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 tyre 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.

Accelera Iota R20 Iota-1 & Iota- st68
The Iota have 2 different types of tread the Iota-1 and the Iota- st68. http://www.acceleratireusa.com/ made by EPtyres 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 tyre. 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 tyres. I didn’t like them. I have recently changed the tyres 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 tyres 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 tyre 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 tyre and the’re OEM as well. Hope this has been some help but realise it may be no help at all!!
