adjusting tyre pressure because i am heavy?

[ENGBen]

Sorry in advance for another stupid question about my tyre pressure.

Ive just been reading my bike manual for my YBR 125 and it says as follows with regards to tyre pressure:

(0 - 198lbs) (I guess this means the combined weight of the rider + his luggage)

Front = 25psi

Back = 29psi

(198lbs - 337lbs)

Front = 25psi

Back = 41psi

Now i am roughly 50lbs heavier than 198lbs... so dont know what to do with my tyres. I want them to be at the proper pressure. Before i had my off i never touched them... i just left them how the shop had them... and got along fine, but since ive got back on ive felt so unstable. My biggest fear is slipping and taking a tumble again.

I know i fell on tram lines before, but every bump or pot hole or manhole cover or scars on the road surface scare the shite out of me.

Right now my front is about 24 - 25psi and my back 28 - 29psi.

How do you guys think i should inflate my tyres?

Also will a normal electronic car type pump do the job? Or a foot pump?

I am not sure what pump I have here, but i will find it today.

I'd check with a shop or tyre technician, that's a big difference in pressures, looks like a typo to me? My Blade runs 36/42.

[ENGBen]

no its defo not a typo

the same numbers were on the sticker on the side of the bike... and in my manual... and in the american manual i downloaded last night.

but yes it is a big difference.

what about the pump? will i be alright with any pump? stupid question i know.... but i wanna do things right lol.

[megawatt]

Most pumps should get up to that pressure ok

ok well if i find the pump i am going to experiment with different pressures this afternoon.

i shall report back with my findings lol

haha

going to try about 35psi see how that feels.

[Throttled]

I realised before I embarked on my first big ride that I too went over into the higher weight for the tyre pressures. It was a bit of a shock

But, I followed the guidance and spent my 10p at a garage and used their air thingy and have no issues since then. So I would say follow the advice as I have had cars which vary their tyre pressure with weight by a surprising amount too.

[techno]

Well if and when I check mine I set them to what it says in the manual, I have never seen 2 different pressures, is this due to yours been a small bike?

Still does seem a big difference at the rear!

And throttled where the hell did you get air for 10p?

[whitedevil]

29 at the rear seems to low for street riding i would try a few psi more and see how it feels. The psi will go up as the tyres get warmer.

Like megawatt says my cbr manual calls for 36 front 42 rear but i find that a bit much for my riding style so i go a few psi under that.

You just need to experiment till you find a good balance you may also need to adjust you suspention as well, something i need to get round to doing as well.

As for the pump, any will do but i would suggest getting a double barrel one if you plan on a manual foot pump type.

Garrage air pumps are usually way off on the psi reading so just be aware of that and check them with reliable pressure gauge. I've used some that have been over 5 psi out.

Good luck with it mate.

There is a nifty pump at the local garage. You set the pressure to what you want, connect the hose and it does the rest.

Have a look on the tyre wall, it will give the max pressure the tyres can be inflated to. Do not go pass that mark. If your as big as you say, l would inflate the tyres to run as if you were running with a passenger, then set about stiffening up the susspension back and front. Hope this helps

I got a ybr 125.

I run the front at 25 psi and back at 35 psi works okayfor me and I aint light and have a topbox as well!

I do find the same as you though that the ybr does feel like its gonna slide out on painted lins,manhole covers etc. mine still has original tyres. Dunno if it would make a difference putting on better quality tyres?????

i use my electronic halfords tyre inflator does the trick - if in doubt check afterwards with a tyre pressure guage.

I have not touched my bike since the weekend when bullet came round and rescued me when my pump broke (and at the same time as the pump breaking, it let my front tyre down to 14 psi lol).

But yes, i think the back is on about 32 right now, front at 25.

Ive read the tyre wall and it says "MAX LOAD 500LBS at 40PSI"

Basically im gonna go to the garage at some point and pump the back one up to about 35 psi.

As for new tyres, i got a quote yesterday for some pilot sportys (suppose to be the best tyres for small bikes)... but your looking at 150 quid fitted.

I could maybe get them for about 125 if i sourced them myself then had them fitted somewhere else.

Still a lot of money tho, which i dont have right now

Yeah they are good, but the one in my area is 20p

[Throttled]

Maybe it is 20p, but I think it is 10p. I am worried now and need to check

Thats 20p too much cos air should be free!

I have learned to live with my stock tyres - mind you i have had 18 months to get used to them now . But in the wet and over white lines they can be a bit of a handful. I have also read on here that the sporty pilots are meant to be good - but thats a lot o muller to spend on tyres if they do not need replacing and do we know if they acrually make a difference!

Keep on riding and before you know it you will have your knee down like rossi (well maybe not go that far but you WILL get used to the tyres and grip)
