Default Whats the weight of your wheel-tyre combo??

I was just watching a Best Motoring video where they were testing the Evo VIII MR with diff alloy wheels and the lap times pointed out that with a decrease of 1.2 Kilos per wheel, the car felt a lot faster getting into the corners and achieved a lap time of almost 0.3 - 0.5 secs per lap.

So, that got me wondering. We talk so much about wheels and big fat tyres but, nobody ever considers the extra weight these new tyres/wheels put on the car.

I just couldn't help but take the spre tyre out of the Vtec and weigh it. LOL

This is what i found.

The spare tyre which measures 195/60 R14 on the stock Vtec alloys at 29 psi weighs exactly 15 Kilos, which equates to a total of 75 Kilos for the 5 tyres combined!!!!

Frankly, i never thought they'd weigh that much.

So, if you've got a spare tyre (the same size as the other tyres), fill it to it's recommended psi and see how much it weighs.

This will give us a better picture as to which combo equates to a lighter yet grippy, investment.

BTW, here's the format.

Tyre Make/Model - Bridgestone Potenza GIII
Tyre Size - 195/60 R14
Wheel Make/Model - Stock Vtec Wheels
Wheel Type (Alloy, Steel etc) - Alluminium Alloy
Wheel Width - 5.5 "
Recomended tyre pressure - 29psi
Combined weight of each tyre/wheel - 15 Kgs.

This test is only for wheels with tyres on and the recomended tyre pressure. get that done and let us know.

No way, ICE, the stock tyre would be much lighter. You're looking at a 2" increase in diameter and an increase in width as well. Not to mention the increase in tyre size as well.

Even i feel it'll be close to the 13 kilo mark, maybe even more. We won't know unless we actually test it.

Does anyone have stock Baleno tyre/wheel on their car?

I mean think about it, for similar rolling diameter, my wheel/tyre are 2 kilos heavier than Iceman's. Reason being that even though i'm on 195 mm, a larger % of the wheel is consumed by the tyre where as in his case, it's the alloy wheel that makes up most of the wheel.

The stocks might just be 165mm but, you can't forget that it's got a 80% profile which measures 132mm compared to the 102mm of the new tyres.

So, what ever the stock tyre loses in terms of tyre width, it makes up in terms of sidewall thickness. And then there's the weight of the steel wheels. If the stocks are tubed, there's gonna be that extra weight of the tubes too.

I must say i was pretty happy to find out that members actually knew the weight of their wheel/tyres !!

Heres mine -

Tyre Make/Model - Michelin MXF sport
Tyre Size - 185/ R14
Wheel Make/Model - Most commonly known as the BSA 282
Wheel Type (Alloy, Steel etc) - Alluminium Alloy
Wheel Width - 5.5 "
Combined weight of each tyre/wheel - ~13 Kgs

And for the stepnee (as a comparison) -
Tyre Make/Model - Bridgestone S322 or S328 or something...either way they are all made of stone.
Tyre Size - 175/ R13
Wheel Make/Model - Pressed steel wheel (without the plastic wheelcover)
Wheel Type (Alloy, Steel etc) - Steel
Wheel Width - 5" ?
Combined weight of each tyre/wheel - ~15.5Kgs

The wheel/tyres were weighed when they were inflated to about 32psi.
Also, might be worth mentioning that 80% of my tread on the MXFs is missing
