Dunlop Sportsmart Tire Pressure


Recommended Posts

Hi all.

 

I am moving on from Dunlop Qualifier tire to Dunlop Sportsmart.

 

I will also change the profile for the rear from 190/50 to 190/55 since Dunlop recommends it.

 

My question is since the Sportsmart is an Ntec tyre, what would be the cold tire pressures to start with. Shall i use those of the 211 tire?

I used to use 30F 29R with the Qualifier and after the session was over i was 4 to 5 psi over that but that was not an Ntec tire. When i tried to go a bit lower in pressures i get flex signs on the sidewall of the rear tire. A point to note is that here in summer we have in the morning 29Celcius and midday 37Celcius and in winter in the morning 17Celcius to 22Celcius midday, if that is needed in consideration.

 

I am an intermediate rider at the track, so your information is highly appreciated.

 

Thanks

hi,

 

 

 

 

 

 

You can find the information you require here. http://www.dunlopracing.com/Pressures.pdf

 

 

 

You will always see tyre pressure rise, maybe 2-3in the front and 4-6 psi in the rear if you measure between cold and Hot of the track pressures.

 

 

 

 

Hope it helps,

As the link that Bullet so kindly pointed to says:

When using DOT approved tires on the street, refer to your bikes owners manual for recommended tire pressures

 

For my R1, it's 33/36psi as I recall.

Paris,

 

I think the 190/55 is better choice. you did good there.

 

As fro pressures, the 4-5 psi rise when hot off the track is normal. you will get that on most any racetrack use of a tire. the hotter they get, the more the rise.

 

As for starting pressure, you need to contact the distributor in Australia directly. I am not familiar with this product in the USA because it is not distributed here.

Here is the link: My link They sell and service these tires, so contact them directly.

 

Have fun at the track!

Hi.

as stated here http://forums.superb...indpost&p=20894 it is a tire for Europe, i live in Cyprus and we have here the sportsmart and not the Q2.

Anyway i will contact the Australia department.

As in the link here http://www.dunloprac...m/Pressures.pdf can i use the N-Tec Slicks UK or USA tire pressures for a non slick but Ntec tire?

 

Thanks

Hi.

I want to share the information i have found about the Dunlops SportSmart where it is the tire used in Australia and in Europe where it is the equivalent or perhaps better ( since it is a newer tire ) to the Dunlop Q2 sold in USA.

 

I did contacted Dunlop Europe, Dunlop Australia and Mr Bullet ( CSS UK coaching staff ) who did a very well write up about Dunlops SportSmart here http://forums.superb...indpost&p=20894 and this is the info i got back from them.

 

Dunlop Europe, Peter Wayte from the Product Support & Service informed me that the Sportsmart has been tested and approved for the GSXR 1000.

 

As per their book suggested tyre pressures for track use: Front 2.1 bar / Rear 1.9 bar, which is 30psi Front and 28psi Rear.

 

Dunlop Australia, Ken Wieden a National Motorcycle & Motorsport Manager of Dunlop Tires informed me that for track day use in Australia they recommend the following pressures for GSX-R1000 ......theye have found these pressures work best there

 

Front 32 - 34 psi hot off warmers

Rear 25 - 26 psi hot off warmers

 

If not using warmers increase by 1 psi

 

If in very fast track day group we could drop rear by 1 psi

 

The above pressures are close enough & are a good starting point ...........we can fine tune to your individual requirements from there

 

For street use :-

 

Front 35 - 36 psi

Rear 42 - 44 psi

 

 

Mr Bullet recommends 30F, 29R. (cold) and maybe as low as 28 R, no more since it is not an ntec tyre, like a d211 or D212gp or a ntec slick. If we run it that low, circa 18-23 cold, it'll feel all squirmy and horrible. It's a marketing related thing, it is not a ntec race tyre, it's a road tyre. Only the track/race tyres are run that low. We wi'll destroy the tyre quickly too. The thing with tyre pressures is that we're always looking for the optimum balance of grip and tyre wear. If the tyre's not wearing or tearing up, and you're not suffering grip/traction problems.

 

So the above is the information about the pressures i gathered for that specific tire where it is an Ntec tire but not a race Ntec tire.

 

I hope i have helped

 

Lets all have a nice day.

Which pressures did you use Paris? How did the tyres perform and wear?

Bullet

 

A day before yesterday i used for the first time my SportSmart ( i placed new tires 3 days before ) at the track with 30F and 29R as Mr Bullet recommended and i was amazed by the safety they inspire me in the corners.

 

What amazed me was even though i went from 190/50 to 190/55 i now do not have any chicken stripes at the rear, where before you could see there was.

 

I hope i have helped someone, as i was.

 

Paris
