Tire pressures do I need to increase for modern tires?

[sidewinder]

Been having a discussion again with a fellow biker in work and something interesting was discussed.when my bike was new the recommended pressures were front 29 psi and rear 33 psi.my buddy said tire technology was not as good as it is now newer tires have a slightly softer compounds.so I was told to increase my pressures by 2-3 psi to compensate for this.now is there any truth in this and should I increase them or not? I don't see any need but some of what he said made sense
Thank you

I would say no. There have been massive improvements in the tyre compound, tread etc but not any that would make any difference to the amount of air needed for your bike. But I am not knowledgeable about such things.

Teflon-Mike:I think I agree with just about all Pinky has said.

I have no clue now getting confused on this one need a tire expert

Take a trip to tyre manufactures site and see what they recommend.....

But many of us do play around with PSI to find something that suits our riding style better.

Most tyres recommend higher pressures if your a fat bugger but aside from that you should be fine. The YBR manual recommends 29 front/rear for less than 90KGS of load and 29/41 for over that (up to the maximum which is 200KGS IIRC).

I've run the same pressure on all my sports based bikes, 36/42.

125s usually 31/30.

It is like OCD to me

mmm, it depends
What bike, what tyres, load, how you ride etc
As said. check specs and experiment.
I find slightly higher pressures suits me

Not knowing the bike /tyres you fitted I say up the pressures
I find as tyre s move on and improve they work better if they maintain there shape
Most older bikes fitted with more modern tyres need a little more pressure

Lower pressure more total grip but less predictable and tends to snap from grip to slide Steering tends to be heavy

Hight pressure slightly less total grip but more predictable, steering tends to be lighter

Watch out converting old inch size tyre (3.50 etc) to modern MM sizes (90/90) as some all conversion table give the largest size of the options and can give poor handling slow steering and tank slapping wobbles

I found using the tyre pressures listed on the Pirelli site for my tyres (rather than those specified in the bike manual) felt like it gave more feedback.
Given I replaced squared off tyres of unknown age at 29/36 (bike manual figures), with the same model (went from 140 to standard 130 at back) at 33/41 (tyre manufacturer's figures), I can't really comment on how the pressures have affected handling as too many variables have changed. I prefer them like this though!

The Continental website just says to use manufacturer's recommendations... Experiment a bit to see what you like?

Unless you're a septic, it's tyres not tires.

Go with the tyre or bike manufacturers recommendations as a starting point and adjust a couple of pounds at a time each way to find your personal settings.

I've always just gone with the bike manual pressures regardless of tyres. Never had any problems i'm aware of - but no idea if i'd be better off with them adjusted a bit either.

Prefer to play it safe n' boring

[sidewinder]

I will just keep the tyres pressures as stated for now.and maybe have a play with them when it finally gets a drier
