Hi Guys,
I just read the review by tsk1979 about the JK Elanzo tyres and though I'd post my review of MRF ZVTS.
I've been shuttling between GOA-BLR for the past one and half year(since I moved to bangalore) with an esteem shod with 175/70R13 MRF ZVTS and they've been absolutely superb esp when it comes to taking abuse, let me start with some background...
Before buying the ZVTS, the only tyres I had experience with was Bridgestone(s322) and Goodyear(GPS2) and JK Tyre(Ultima) , the worst experience was with the JKs, they have always ended up losing their round shape and developed bulges on the side walls. The Bridgestones and Goodyears were quite good except that I had noticed that the bridgestones ended up with cuts on the sidewalls due to my hard driving over bad roads - but their grip was pretty good (compared to the JKs)
I changed my job to a bangalore based company in late Jan of '08 and moved to bangalore, I had come back to Goa for the weekend and decided to take my (t)rusty esteem to bangalore. But the esteem had really bad tyres (the JK Ultimas on their last leg!) I was worried whether I'll make it to Bangalore with them.
So Went around in Ponda searching for tyres - had decided to upsize to 175/70R13 instead of the 155/80R13, Ponda is a small place and I couldn't find any place that had anything other than JK, MRF and CEAT ! And it was already 7pm so there was no way I could go to Panaji and hunt for tyres there (as almost all shops in goa shut down by 8.00pm ).
Since tyres are something you have to live with for quite some time and I was looking to buy the Turanzas, I was very sad and disappointed!
However since it was late in the evening on Saturday and I had to leave for Bangalore the next morning - I decided to buy the ZVTS consoling myself that they'd wear out soon if I drive hard enough

and the next set I can buy better tyres. The cost for ZVTS was something like 2.4K per tyre+tube combo and I bought 4 tyres as the spare JK was pretty decent.
Now for the actual review...
Positives first:
The tyres are virtually indestructible !
I've driven through bad roads, no roads, at insane speeds so much that I've had bits fall off the interiors and even have ended up with bent suspension lower arms on two occasions!
The the tyres have gobbled up whatever I've thrown at them, they've been driven on very rough roads at triple digits speeds(where people wouldn't think of doing even 50!) with me pretending to be a rally driver
I've driven at 3 digit speeds in the night through the hubli-yellapur stretch, and bent suspension lower arms going over potholes covered with water - but nothing, I mean NOTHING happened to the tyres, they just chewed all the abuse I threw at them!
After 30K KMs of hard driving(Mostly GOA-BLR runs), there no signs of anything abnormal like bulges, tears, cuts or anything ! In fact there's a lot of tread left - discounting one tyre which got a little abnormal wear due to a bent lower arm and wrong wheel alighment, the other 3 tyres look like they can do at least another 40K kms of abuse if not more!
Another good thing is that on mildly rough roads, I "feel" the ZVTSs absorb some of the roughness, I don't know if this is really happening or I feel that way because of the ad about "the most comfortable radial"
The negatives:
The ZVTSs have scared the daylights out of me when I've had to brake hard in a couple of tight situations and a few times when cornering at the limit in the anmod ghats.
The way the ZVTSs grip is a bit weird, at least my experience - when they give up and lose traction - instead of gradually losing grip they just snap. For example, in the ghats when cornering hard, the rear would hold for sometime and when it was too much to handle, they abruptly snap free! The rear end slides and then I have to frantically turn the other way round and floor the accelerator holding on to dear life - the first few times it happened, I had my entire life flash in front of my eyes in a split second, but later on I got used to tackling the situation when this happens (also have found what's the point where the tyres "snap" and try to not push it to that point)
Another negative is that, when braking in an emergency situation at high speeds (110+) , the ZVTSs tend to lock up very early and can be very scary.
I've had to brake hard at 120 Kmph when some guy on an activa(in karwar on the straight, parallel to the sea - just next to the road where you enter the city) suddenly decided to start his skooter and take a U-turn in the middle of the road without looking behind(he was parked off the left side of the road), the tyres locked when I panicked and braked, with the car skidding towards the guy - who froze in the middle of the highway. For some reason I tried decreasing the force on the brake pedal(don't know if I thought or it was just a reflex!) to unlock the wheels and the car slowed down a foot or so away from the guy on the skooter - much to my relief !
Conclusion:
The ZVTSs are very strong and virtually indestructible tyres in my experience, maybe MRF developed them from whatever they learnt in rallying !
Whether I will buy another set of ZVTS - well most probably not at least for the esteem. Their characteristics when driven to the limit or when braking hard are something I'm not very comfortable with - esp. since I do a lot of relatively high-speed long distance driving. Although I might buy a set for my M800 that gets driven in and around Goa.
Would I recommend ZVTS - well if you've to drive a lot through bad roads and need tyres that can last long, really long - go ahead and buy them!
These tyres are not the best for any remotely fancy driving at high speeds, however for most of the folks who would never have made a tyre squeal on cornering, these tyres IMO do their job really well. Also I think driven properly and cared for, they might last at least 90K kms !
