Why is XM2 Plus not in anyone's list for the Crysta? Just wondering.

Extra Load marking is a gimmick and doesn't really indicate how robust a tyre's construction is. Number of plies on tread and sidewall is a better indicator.

Good point and should not be missed whilst making purchase decisions The UC6 101 upgraded to and P4ST 101 (previously used) have 2 ply sidewalls and both also have extra load marking on the sidewall. But why do you say the marking is a gimmick?

XM2+ 205/65 R16 is the only size it is available compatible with Crysta and is not available in any plus (upgrade) sizes.

For reference, I'm attaching a load vs pressure table for the 205/55R16 size where normal load index is 91 (615 kg) and extra load is 94 (670 kg).



As you can see, the extra load tyre does not increase the load carrying capacity of the tyre at pressures upto 36 PSI (250 kPa) and to derive the benefit of the additional capacity, one would have to inflate the tyres to 42 PSI (290 kPa). Funnily enough, it's not a legal requirement to mention that the pressure needs to be increased. Case in point, on both standard and extra load tyres you'll only see "Max Pressure : 350 kPa/51 PSI" marked on the sidewall, which indicates maximum safe pressure.

In addition, it is not a legal requirement that extra load tyres have 2 polyester plies (though you're right - most of them do have - mostly because india is considered a high severity market). Single ply tyres can very well meet the legal requirement for "XL" markings, and such tyres are indeed sold around the world - especially in Europe, where "XL" tyres will have a better rolling resistance label value - not because of what goes in the tyre, but because XL tyres are tested under a different load and pressure compared to normal tyres - Higher load and higher pressure = better rolling resistance.

I have personally seen grey market imports - tyres not specifically designed/made for India but imported and sold - brands like Hankook, Nankang, Triangle, Kenda, etc. - with XL markings but having only a single ply. This is especially common in sizes like 215/45R17 which is a popular fitment on heavily modded Swifts, Balenos and Polos here in Gurgaon and in Punjab/Chandigarh.

Hence I would say that regardless of whether the tyre is marked standard load or extra load, check the sidewall marking for the number of plies, because that is what would make the difference when you have an impact damage from a pothole:

Single ply - getting stranded on the highway due to a fully deflated tyre from a sidewall cut
Dual Ply - even a severe impact causing only a bulge, which still retains pressure and keeping you mobile till you can have the tyre replaced

Hello bhpians. Is it okay to upgrade the innova crysta's tyre size to 225/60 R17? Did anyone try this size? Ours is currently running on stock size of 215/55 R17.

The increase in diameter for the proposed upsize exceeds 4% and is not recommended. Would suggest you go for 215/60R17, or perhaps 225/55R17 if you're looking for wider rubber.

During 70,000 kms service for my Innova Crysta, I complained of steering vibrations at speeds of 108 kmph and above ( 98 kmph GPS speed ). After inspection, they mentioned that it's due to bent alloys. I asked them to put the best 2 alloys at the front and the reply was that all 4 alloys have some level of deformation and that they will put the best 2 alloys at the front.

Moral of the Story

I'm done with the 17 inch low profile tyres on my Crysta. When the time for next tyre upgrade comes, I'll change all my alloys to 16 inch alloys. Hopefully, I'll get the Touring Sport version alloys for 16". I had seen these in a few innovas manufactured during the notorious tyre burst issues on the 17 inch tyres.

Tyre Sizes considered

• 205/65 R16 - Safest option. But, from the threshold of ABS kicking in on the Crysta even with 215/55 R17 ( indicating a loss of grip ), I feel 205 is a bit low for such a heavy vehicle.
• 225/60 R16 - This looked the ideal size for me since the change in circumference is just 1.2 % compared to 215/55 R17 and it also provides 20 mm of additional grip. Sidewall height even though not as good as 215/65 R16 was still a decent 135mm just 4 mm short of 215/65 R16. But, since the alloys are 6J, and the recommended max width in the alloy is 215 mm, I had to give up this option as well.
• 215/65 R16 - Decided on this size due to same width as 215/55R17, and the hefty sidewall of 139.75 mm ( vis-a-vis 118.25 mm on 215/55 R17 )

I researched on good tyres available on this form factor and sorted them based on load index and then on speed. This is what it looks like.

Driving style / other factors

• Highway:City drives - 60:40
• Highway driving style - Try to be on cruise control at around the max allowable speed on the road. There could be occasional bursts to upto 1.3x the speed allowed. But, that's very rare and the only reason to do that would be to get away from bad drivers driving at around my same cruising speed.
• City driving - I do not baby it on the broken city roads in Bangalore. I would try to avoid pot holes. But, sometimes it can take an impact at speeds around 20 - 30 kmph.
• Can encounter frequent wet driving conditions on the Western Ghats and in Kerala.
• Love driving on the hills even if the road is bad. The frequency of such drives might be low. But, given an opportunity, I grab it with both hands.
• Vehicle can be fully loaded during 700 kms drive to Kerala or Hyderabad.
• Typical temperature range under which the vehicle will be operated - 5 degree celsius to 45 degree celsius.
• Comfort and safety is a priority.
• If the chances of family being stranded midway during a trip can be avoided, I am all for it.

Based on this, any recommendation on which tyres to choose ?

PS: I will be replacing the alloys with 16 inches only after 10k to 15k kms since there is that much of tyre life left and I do not want to contribute to more environmental junk in addition to the 17 inch alloys.

I'm planning on doing the exact same thing with my Touring Sport as well. I upgraded to 225/55/17's last year and while they were marginally better than stock, they are nowhere as comfortable as the 16" wheels (stock) that are available on lower variants.

I tried getting the part number for the 16 inch Touring sport alloy wheels. But, they keep sending me the part number for 17 inches instead. I have kind of given up on Nandi Toyota on this and if they are only giving me the option to replace with 17 inches, then I won't budge till they agree to replace it under extended warranty. If I replace these 4 alloys, that will be the 5th alloy replacement in 70,000 kms of ownership. And they are not cheap by any stretch of imagination. They cost 19,000 INR for an alloy wheel. That equates to 95,000 INR for alloy replacement after 70,000 kms ( 1.36 INR per kms just for alloy wheel replacement! ). All for the stupid design choice ( low profile tyres for such a heavy vehicle running on pothole filled Indian roads! )

PS: In case you are able to get the part number for the 16 inch Touring Sport alloy wheels , please share it with me as well. I'm sure Toyota did sell Touring Sport Crysta with 16 inch alloy wheels for a few months during the notorious tyre burst incidents on 17 inch models.

I like the brushed metal alloys on the facelift better. Black alloys only look good when new and need to be maintained well. Else it would look like an eyesore.

Guess by the time my Crystas tires wear out, I will also join the queue of alloy replacements. Absolutely stupid idea to provide such a rim which can bend easily on what is supposed to be a rugged MPV. Apparently two of my rims have these runouts in 22k kms.

Do they have a 16" version of it ?

I'm not sure if they are OEM, but they look very very close!

The pre-facelift ones are available as well

Yes in the facelift both 16 and 17 inch alloys are black with brushed metal finish. Hence am inclined towards that. The pre facelift 16 inch alloy looks too boring IMO.

I saw a Crysta being fitted with 235/60 R16 on stock 16 inch wheels. The overall diameter is within 3%, but 235 on 6J is NOT generally considered OK. The sidewall bulge due to narrow rims and when driven away the flex was excessive (rim on tyres) causing vehicle to roll sideways. It will be super comfortable on broken roads that's given. The tyres do look good and tread wear rating on this CCLX2 is 540 compared to 340 of the UC6 (similar for P3/P4 ST) i have on mine.

A 5th alloy was bought new from Toyota and they installed my old Michelin Primacy 3ST on it to use as spare wheel.

[SR7]

The stock tyres (Bridgestone Turanza 215/55/R17 94V) on our 2016 Innova Crysta 2.8 ZX AT are due for replacement.

If I upgrade to 225/55/R17, overall diameter increases by 11mm for a diameter variance of 1.65% but sidewall increase of 4.65%

I’m concerned about the harsh ride quality of the stock 17” alloys on 2016 top end AT models, but would upgrading to 225/55/R17 impact the performance of the ABS, ESP & TC systems? That is my primary concern - if that active safety systems will not be affected, the added 11 mm would add to the ride quality.

Also please suggest the make & models of the tyres. Would continental or Michelin be better than the Bridgestones for comfort & ride quality? If conti or Michelin, what model & load/speed rating? I’m only starting to learn about tyres, so would appreciate the inputs of experienced experts in this regard.
