When i'd gone to Whitefield Honda to get my car serviced. I noticed this amazing looking tyre which was displayed in one corner of the showroom.

It had this typical V shaped tread pattern, seen on most performance tyres including the Goodyear GS D3s. The tyre looked neat and had a low side profile.

The markings on the sidewall read 195/55 ZR 15. ZR!!!! Woww, this was actually a Z rated tyre.

We picked the tyre and checked out the sidewall to see how it was diff from the others. I tell you, it's sidewall was as hard as the contact area. Felt like it was made of stone.

We aksed the Honda guy how much each tyre would cost, he went in and came back in a while. You wont believe it, the price was around 5400 each!!! For a Z rated tyre????

Wow........ I dunno how good they are, but i can tell you one thing. With a sidewall like that, potholes will be scared when this guy comes rolling towards them. LOL

The tyre i saw was similar to the ones on this link, click here.

I did a detailed study on tyres and the dealer for them in Blr is Super tyres on JC road . Well these tyres look good but dont know much on how will they perform coz however inquired form diff mkt sources and did not get a good review. A tyres performance will be noticed only after a few kms are run in as to tread wear . As per their price in the foreign mkt its the lowest so i dont know how are they selling these tyres with the prices that match the goodyear and michellin they are well low abroad.

I saw the Federal tyres too yesterday with a wierd V pattern looked sporty but the dealer told me that they were sport wet tyres and asked the dealer regarding the cost for a 205/60/15 and he told me that they were for 4850 each. Spoke to a couple of friends and they assured me that the tyres are pretty good.

Guys,

Even within a normal budget...always go with a tyre company that has extensive and consistent R&D activities (Bridgestone, Michelin, Goodyear etc.). Tyres are the only contact between even the most sophisticated suspension and the road.

Looks aint everything, and Federal buyers will realise that sooner rather than later.

True, for me it's only Bridgestone.

Hey wait a min!!! Read the tyre size again. it says "225/40 ZR 18 - 88 W" Now 88 is the load rating and W is the speed rating, so what in the world does ZR stand for? R is radials, so what is Z??? Can't be Z rated.

i think the Z stands for the speed rating , the max speed at which the tyre is ok... or something like that. I read somewhere that most tyres have an alphabet before the letter R, which can be anything from P to Z (although we dont see this in indian tyres), with P being the lowest speed, so i guess Z would have the highest speed.

Jus checked here...

Ok, actually there are two things we are looking at... the "z" is part of "ZR" specification, and the W is part of "88W" specification as shown on the tyre. 88W is also called the "Service description" and in this case, 88 is the Load Index which corresponds to a max load of 560 kg that the tyre can take and W corresponds to the max speed of the vehicle to which this tyre may be fitted, which is 270 kmph. For example, a tyre rated 225/40 ZR 18 - 88 W can sustain speed of 270 kmph under max load, which is denoted by 88. Whereas a tyre rated 225/40 ZR 18 - 88 Y will sustain max speed of 300kmph with load corresponding to 88 index. The ZR rating just means that the tyre will funtion properly at speeds in excess of 270 kmph.
ZR also denotes a stronger sidewall than the plain R rated tyres.
