Method Used for Tyre Upsize Calculation

There is not much scope to increase the Total Diameter of the tyre that comes originally fitted in your car.

    Tyre Dimension Measurement
    Total Diameter = Wheel/Rim Diameter + Sidewall

This total diameter can only be increased by 3%, for a safe upsize of tyre. So, we calculate the total diameter for each tyre size and then compare this with the total diameter of the size that is originally fitted in your car.
If the difference lies within this range of 3 %, then only we would recommend that tyre.

Hi Abhishek,

Well, those are a plenty of options to choose from. So I would try to narrow things down and help you make an informed choice.

1. If budget is not a constraint, then I would suggest Michelin Energy XM2 Or Bridgestone Turanza AR20. While both these tyres would offer excellent wet and dry grip, very responsive braking, superb ride comfort and long tread life, Bridgestone would be a bit more durable on rough roads while Michelin would offer a more comfortable and quieter ride.

2. If you want something economical then go for Yokohama Earth 1. It comes with a silica infused tread compound and hence offers superior wet and dry grip and long tread life. Even the handling and comfort would be very good, albeit not as good as with Turanza or Energy XM2.

3. In case you want something more economical, then you can look at Bridgestone B290 or Goodyear Assurance Triplemax. These tyres offer confident wet and dry grip and adequate ride comfort. Both these tyres offer similar performance, but Bridgestone would offer longer tread life.

4. If you drive over rough/ unpaved roads then go for Bridgestone Firestone FR500. It offers confident grip and performance, and is quite durable to rough surfaces. Also, If I am not wrong then Bridgestone is offering unlimited 2yrs warranty on Firestone tyres. You could check about this on their website.

Hope this helps.

Ramit

Hi Raghu,

Glad to know that you own a well-maintained Maruti 800 1995. However, I am sorry to tell you that finding decent Bias-ply ( Non-radial) tyres in size 5.65-12" would be a very tough thing. This is because almost all passenger car tyres  these days are radials.

And even I would suggest you to use radial tyres as they offer better handling and performance.

For your 800,you could look at Goodyear GPS2 tyre. It is a decent option to begin with.

A better option would be Falken Sincera SN835.

And in case you want exceptionally good tyres then go for Michelin Energy XM2.

Regards,

Ramit
