Maruti Suzuki Jimny : Tyre & wheel upgrade thread

To those looking forward to a tyre upgrade but wondering how the tyre size of their choice will affect the dynamics of the vehicle, take a look at this list made specifically for the Jimny (or any vehicle with a stock tyre size of 195/80R15 for that matter). The list is only for 15inch tyres.

Do note that the 2nd column from the right (percentage of change from stock size) is what matters the most. While a 2% to 3% change is the maximum recommended by most vehicle and tyre manufacturers, the closer it stays to ZERO, the better it is. As the %age of change increases in the positive direction, acceleration & engine braking will proportionally degrade (the brake pads and brake shoes will also be under a bit more strain for long downhill slowdowns with a full load of people and/or cargo) while top speed and fuel efficiency will (theoretically) increase. Similarly, as the %age of change increases in the negative direction, the effects will be just the opposite. Oh, and then, needless to say, there is the issue of speedo & odo error.

Tyres wider than 215mm might require a rim change as well, so to get an idea about that, check out this website (which I felt is reasonably informative) https://www.tyresizecalculator.com/c...rim-size-chart

Cheers.

Well done and thank you for taking the trouble to share this.
It is absolutely prudent and sensible to pay attention to this aspect instead of getting carried away by the ‘look’ of all those monster sized tyres.

If you would be so kind as to do something similar for the Mahindra New Gen Thar, it may prove very useful indeed, considering the sheer numbers out there and the extreme propensity of many owners, to do big time tyre upgrades.

Great work! Thanks for the effort.

Can you also add a column on "availability in the Indian market"? Many of these sizes are theoretical as they are neither made here nor imported

Great compilation - will definitely be useful for prospective Jimmy buyers.

Another factor to consider is whether the wider tyres will foul with the fender or bumpers on extreme right or left lock.

The Jimny is a hotly anticipated model & owners of such cars are known to splurge on modifications (tyres are usually the first upgrade). Wait for the launch = you will see the most popular tyre upsizes freely available. As an example, for the Thar, the 285/60 R18 AT (a popular upsize) can be arranged at any tyre dealer in Bombay. What's more, you have two brand options, Maxxis & BF Goodrich.

Re: Maruti Suzuki Jimny : Tyre & wheel upgrade thread

215/75-15 is the sweet spot for the upgrade.

However given the lower power this will further sap performance.

Anything more than 215 is counter intuitive as it will slow the car down and make it worse to drive.

Yokohama Geolandar A/T is available in that size.

Best to see which size appeals to you and check availability with your local dealers.

What is available can itself vary from time to time and place to place. Doesnít seem to make sense to research this across the board. Itíll be dynamic info in any case.

Hi.

Please view the attachment. I have included most of the tyre sizes that I feel might be of interest to people.

I am not sure whether all sizes mentioned are available (or even being manufactured at all). However, the list should be helpful to any person who already has one of the included sizes on their mind.

Happy to be useful,
cheers.

An extremely important point! With the limited BHP & Torque, it's best to maintain the Jimny's agility with a moderate tyre upsize. Nothing too fat.

One of my favourite A/T tyres .

Re: Maruti Suzuki Jimny : Tyre & wheel upgrade thread

Also need to consider the rim width. If going with 215 section tyre, the rims also needs to be upgraded to wider ones

The sweet spot without doubt, and very convenient as well for prospective Jimny owners, because this size is available with quite a few manufacturers in both HT & AT construction.

About the Yokohamas, I too use the Geolandar AT G015 (205/70R15) on my present vehicle. I have installed them on the rear axle of my 2008 Innova. The comfort levels are better than the stock bridgestones but a bit lower than the Michelin Energy XM2 that the Yoko's replaced. I have felt that grip on the tarmac is much better than the Bridgestones and significantly better than the Michelins. When on gravel roads, the (road biased) Michelins used to struggle and I wouldn't dare take them over rocky surfaces, but not anymore with the G015's. I am very much satisfied with these tyres on the dirt roads I occasionally traverse and also on highways.

However, in the past, I have used Goodyear Wrangler RT/S and later, Michelin LTX AT tyres on my Gypsy (bought 2nd hand in 1999, sold in 2007). The Wranglers were good but the grip levels and tread wear on LTX AT's were incredible. There would be much lesser wheel spin on gravel inclines, sometimes while reversing in 2WD (convenient in not having to slot it into 4Hi just to back up a bit and then having to slot back into 2WD). Unfortunately I couldn't find those tyres anymore. A newer LTX-AT2 version is available but I felt the G015 had more sidewall protection.

Continental has a new made in India model, called Conti 4X4 Contact. The tread pattern on these are actually highway oriented so with the Innova being a RWD vehicle, I got them installed in the front. Straight line braking is good, but unfortunately, ride comfort has taken a blow.

Attaching a couple of photos of the tyres I now have.

What's the OEM rim width? You might be ok with 215 on OEM rims.

I do not know the OEM rim width. Usually, OEM rims support upto one upsize interms of width. Since OEM tyre spec is 195/80R15, I think upsize to 205 section would result in optimal use of the upsized tyre. 215 section, on stock rim width may result in rounding up the tyre thereby not benefitting from the additional 10mm width over 205.

Just for everyoneís academic interest, the OEM Gypsy Tyre is a Nylon Cross Ply F78-15. The MSIL recommendation for Gypsy in Radial tyre has always been 205/70/15. These were a bit hard to get in the 1980ís and 1990ís and even the early 2000ís, hence many of us Gypsy owners went for radials in 215/75/15. These worked. Yes. But the edge of the larger radial tyre was always dangerously close to the sharp under-bumper-edge in the front in the stock Gypsy. So some amount of light grinding had to be done. Or a complete bumper swap to an off road type.

Going by the above, I would probably go and check which size is best for the new Jimny. While 215 AT seems highly desirable, 205 AT is what looks and sounds sensible. But better to check in person when the physical vehicle is present.

Here are pictures of the Jimny I saw in 2018 in Dubai.it had 215ís on. But it also had Ironman suspension and might have been lightly lifted too.

The stock Indian Jimny comes with 195ís and a high sidewall as can be seen here too. This makes for excellent ride comfort. For this reason alone, the best upgrade as per me, would be 205ís with a similarly high sidewall. The only reason I would even consider an upgrade is to get a set of nice AT tyres on, instead of the OEM road biased HT tyres.
