Tyre pressure is a funny thing.

This is the first Suzuki I've owned that recommends 36f/42r.

Every other Suzuki I've ever owned (TL1000S, SV650 and GSX-R600) have all recommended 36f/36r ...... so why the change? More tyre life? Different tyre construction? Suspension settings?

I've also owned a Brutale which recommended 33f/33r ..... more grip at the expense of tyre life? Who knows?

Either way, I always run whatever the manufacturer recommends.

I also always try and stick with the tyre brand (eg, Dunlop) that came with the bike from new, because the tyre pressure recommendations were set with that brand. If I change brands (eg, Pirelli) I go to the brands website and check what air pressure they recommend for that tyre.

If you stay with stock tires on this bike I think you're really missing out. Also, I've only seen manufacturers give maximum inflation pressures, not pressures for specific bikes, but maybe some do? Not sure why a tire maker would want to second-guess the engineers who designed the bike.

Tire pressures should be adjusted to the recommendation of the tire manufacturer, not the bike manufacturer. The bike manufacturer calls for a specific model OEM tire and the pressure specified by the bike manufacturer for that tire is what the tire manufacturer recommends for that tire. If you run a different tire then you should run the pressure recommended by the tire manufacturer for that particular model tire.

I have always run with 36F 42 R - which is recommended. However, there is an article in the latest (January 2019!) Motorcycle Sport and Leisure who are running a 1000F as a test bike. They change the tyres from the Dunlops to the Bridgestone T31 - primarily coz the T31's will be better for wet/cold riding - he gets a much bumpier ride at pressures of 36/42. The tyre specialist explains that for solo riding it should be 32F 36R and 36/42 is for pillion /heavy luggage. I have followed suit - i.e. have had T31 fitted and will run with 32/36 solo - if anyone is interested I will give feed back later - not that there is much opportunity for riding at the moment with temp at zero to 4 c!!


I have emailed Bridgestone UK to double check but no response so far.

Hi, How did it work out?

When new in February it had R42 F36 but it was like a bouncing basket ball. I adjusted it to R29 F25 and have not touched them since then.

With that being said, tire pressure does have an influence on ride quality.
Absolutely. But I think this should be done while dialing in the suspension for max benefits. The poster may well have done that already. I just wanted to point out for noobs so they dont try to adjust their ride solely on tire pressure. Good grief 🤦‍♂️🙂

Not to be a jerk, but you should adjust the ride quality with your suspension, not your tires.
Of course, the suspension was the first thing that I adjusted.

Those pressures are really low for street riding IMO.
I use this bike for FWY ridding not for street ridding. I weight 140 lbs. Also temperature in California is very hot, we have been getting 112 F (44.44 C) max in Los Angeles. I believe that considering these factors my tire pressure is optimal. Better breaking, better curving, less chances to get a nail, better absorption, tires last longer, less chances to sliding, better griping, etc.

30-30 there's a lot more feel and it doesn't feel like it's gonna fall over in the corners especially going from the pavement to concrete corners
I'm running Dunlop roadsmart 11 180-55 rear 120-60 front

Lol just asked the 180x55 question. In defence of your pressures, tyres can play upto 20% of suspension. Imho.
