@joe: Good you went for the right upsize this time. Alls well that ends well. Relax now and enjoy the ride.

Well, the width of the tire you can put on a rim depends on the width of the rim. Every tire width has a minimum, maximum and recommended (optimum) rim width. It is always recommended that the rim's width is optimal for the tire's width.

If the rim's width is minimum, the tire's sidewalls will flex more than optimally required - affecting tire wear, cornering capabilities, etc.

If the rim's width is the max, the tire's sidewalls will flex lesser than optimally required - giving you a stiffer ride, as well as affecting your cornering abilities again.

Look up the tire bible if you are interested in knowing more

I would say it was a good decision done. Atleast the dealer was nice enough to take it back and charge only a mere sum for a swap. Sometimes, guys are so arrogant they say they cannot take it back or they will buy it at half price etc.

So, thank god and always be careful when going in for such upgrades

You got a good deal. 1000 rs is reasonable though he should have recommended you the proper tyre upgrade size.

You know what, i think i ran over 500 kms on the previous 185/702/r13, and i use to admire the tyre grip and ride quality, I use to maintain 27 psi for the previous one, but with my stock recommendation that is my current upsize 175/70/r13 i m maintaing 26 psi as per company recommendation, but i feel little bumpy ride.... any idea why?

Hi Joe,

Firstly, please note that you have NOT upsized your tires!! You have just gone back to the stock size (175/70/R13) which comes stock on the Esteem Vxi anyway. An upsize/upgrade would be 185/65/R13.

With regards to a slightly harder ride, the reason is because of the increase/decrease in the aspect ratio (height of the tire from the rim) of your tires between the two sizes as explained below :

175/70/R13 - In this case the aspect ratio is '70'. Which means the height of the tire from the rim is 122.5 mm.

185/70/R13 - In this case again the aspect ratio is '70'. But due to the increase in width of the tire whic is 185 mm; the height of the tire from the rim is now 129.5 mm which is 7mm more than the stock size and hence gave a better cushioning effect.

Hope the above helped :-)

That's only expected. Compared to 185/70, 175/70 is narrower (so lesser grip) and also has lesser height (so reduced cushioning effect). More tyre height means shocks from road undulations have to travel greater distance, lessening the shock impact.

Yep he's right. It all depends on the rim width.
I think esteem comes with 5j rims, you can get alloys of 5.5j rim size. this increases the width of the tyre.

Reviving an old thread.

I understand the best upgrade for Esteem vxi is 185/65/r13. However I donot see any available in the market in that size.

Is anyone aware of the availability of that size?
