I am honestly very surprised by some of the comments here.

Will the reaction be the same if a Fiat, Tata or Mahindra downsizes the wheel and the price of the vehicle remains unchanged?

The Crysta is already priced ridiculously high. Well, let them fleece Indian customers more, as long as we don't mind...

- Higher unsprung weight (metal weighs more than rubber)
- Tendency to tramline

Other than looks, there is no other advantage. But as is obvious, the cons far outweigh the pros.

Wouldn't the impact on ride quality depend on how the manufacturers have tuned the suspension. Most reviews including Team BHPs rate the Hexa handling very highly. I think Toyota may have optimised the suspension for 16 inchers and then used 17 inchers. It is infact surprising that a 1 inch upsize which is very commonly done should degrade the ride so much.

Drive on,

Bigger diameter wheel tyre combination can provide good ride quality as long as the tyre profile isn't too low for comfort. Manufacturers tune the suspension keeping the tyre aspect ratio in mind. Ideally i would have preferred a 215/60r17 which is within the 3% diameter allowance as compared to 205/65/r16. This combination would have provided the best compromise between ride and handling not to mention much better proportions with wheels filling up the fenders much better.

Hi.
I see a tyre bulge in my crysta 2.8 ZX. Its a 17inch stock rims. I have heard owners saying service center will change it to 16inch rims with a big sidewall profile tyres.

My question is if i opt for an after market 17inch rims with a big side wall profile than the stock ones will i face the same issue ??

Need some advice on this issue ASAP.

The overall diameter of the wheel (rolling diameter) should not change. So when you go for larger rims, the sidewall needs to be thinner. If you don't keep the same overall diameter, you will have issues related to speedo meter error, rubbing the wheel well or suspension parts while steering and even speed vs gear change relationship changes in case of ATs. More importantly any suspension related warranty claims may get denied. Overall never a good idea.

2% change is typically allowed.

So is it not advisable to go for a 17inch rims with a little bigger sided wall ?

If the problem is on your tyre and you want to keep 17-inch rims why do you need to buy after market rims? Just buy higher profile tyres and use on OE Rims, you may notice small speedo error but that should be marginal. Best will be to check with local tyre shop for an advice considering availability/prices. You can also use a different brand than OE in the same size and try your luck, I have seen some tyres performing better than others even if sizes are same. Again, find a large tyre shop in your vicinity and go by his suggestion but no need to buy local 17inch rims, if nothing works out check with Toyota for replacement, maybe they will cover you under replacement without a charge.

Thanks to a Team-BHP fan (who prefers to remain anonymous) for sharing this info!

With the change in Innova's tyre size to 16", there are thousands of 17" 215/55-17 Bridgestone tyres being sold at throwaway prices.

Dealers are being offered this tyre at Rs. 7500 all inclusive. So, a fair margin would be 10-15%. But many unscrupulous dealers are still quoting 12-13k per tyre and minting money.

The tyres are brand new. Being offered to dealers by Bridgestone, but unofficially.

So, some dealers (maybe 5-7 in the whole country) have each negotiated with Bridgestone directly for a large quantity of tyres. Maybe 5000 or 10000 tyres of this size. Bridgestone have offered it to them at a loss (because otherwise, they would never be able to clear this stock as the Innova is now 16").

These dealers have taken a risk & purchased it, and are now offering it to other smaller dealers at very good prices (Around 7500 as mentioned).

And everyone is trying to maximise their profitability!

With the updated Innova Crysta, Toyota has gone back to the 17" tyres for the Z variant! I'm not sure what the logic is this time.

[akshay380]

But crazy to the a brand with such perceived standard checks and quality doing flip flops with such an important element of car!

Autocar has come up with an article on this - http://www.autocarindia.com/car-news...-crysta-405938

Quoting the relevant part -

As a part of the update, the carmaker has restored the Crysta with 17-inch rims that has tyres with a stiffer sidewall.

[karan561]

Stiffer side walls may not work.

But 225/55 R17 would work & that should have been the correction instead of the 215's.

I am sure Toyota would have spent careful time with the Tyre manufacturer this time around.
The 16inchers were most likely a stop gap, till the correct solution was found out.

[androdev]

215/55R17 on Innova! We can expect to see BMW owners and Innova owners socialising in the tire shops when they come to replace their cracked tires.

Hopefully taxi guys will stick to 16" wheels and let the city slickers buy the 17" wheels.
