Accelera Iota

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!!

I am going to be totally honest about these tyres.

IF like me, you have a LARGE HEAVY SUV (BMW X5) and you don't race it on the streets because you are not 19 any more... then these tyres are the BEST you can buy pound for pound! They where fairly well, they dont last so long on my X5 because of the rear camber on the tyres is not adjustable and there for the inner tyre shoulders wear out every two years.

They do the job, they are ROAD tyres, NOT off road. Even still I drove into a car part at the goodwood festival of speed that was soo muddy that they would ONLY let 4X4s park in as other cars got stuck and I was pretty worried with my x5 and its road tyres competing with some Landes and serious 4x4s. I have to say, it wasnt as composed as the Discovery infront of me but... it got the job done. Was pretty proud when I jumped out and they guy in the disco said "I didnt think those things did well off road?" I said well... I was pretty nervous but... I am hear! :D

Brilliant tyres - Accelera Iota ST68 - 285/35/R22.

I have had many vehicles over the years and many tyres such as - Goodyear Eagle Ventura & Eagle F1 & GT5, Pirelli P6000 & PZero's, Vredestein Sessanta & Cento, Falken FK451, 452 & Asensis, Khumo Ecsta Le Sport KU39's etc etc so I know my tyres!!

These Accelera Iota ST68's (a full set of four) replaced the Falken Asesnis on my Audi Q7. The difference is like night to day! Simply brilliant and they have transformed the car at a saving of £66 per corner compared to the Falkens. Job done!

Ride was choppy and noisy with the Falkens....now gone. My tyres are on 22" so I will always expect noise as they are 35 profile but these Accelera will blow away any other tyre. I have today just hit massive standing water doing 65mph and not a flicker.....straight through. Can't comment on tyre wear yet but that doesn't bother me as I will replace like for like anyway and the Falkens only gave me 9,000 miles on the front and were down to 2.5mm!

The car is almost 2.5 Tonnes and 3.0TDI Quattro so has a whack of torque and demands a lot from tyres……especially when you stuff it into sport mode and paddle shift……sweet!!!

No snow yet so can't comment. Dry grip excellent, so is wet grip, noise is almost non existent, ride handling excellent and fuel economy.........it's a Q7 so is thirsty regardless of tyres!

So I give these 100%. Brilliant!
