    Front tire wear

    Hi All,

    Tried the search but couldn't find anything.

    I got almost 20000 kms from the the OEM Pirellis so when time came to replace them went with the GT A spec tires expecting to get at least what I got on the STs.

    The rear tire is performing well, coming up to 20000 kms with some wear from the center of the tire but still lots of room to the wear bars and no cupping or scalloping.

    The front tire is a different matter. It lasted about 12000 and had significant cupping and scalloping when I replaced it. Now the replacement tire for the original GT A has about 7000 kms and is starting to show signs of scalloping, but no cupping.

    I keep the tires set to 36/42 (cold) and check them before the first ride of each day. I ride solo with panniers but no top box and ride in what my friends call a conservative manner with a slightly less conservative manner in the curves. 

    I'm wondering if there could be an alignment issue with the front wheel ... any ideas?

    best regards,

    Shemogolee

    Shemogolee. I love to know how you managed 20,000 kms. from the original Pirelli's. I don't doubt you for a minute, just amazed. I currently have the Michelin PR 4 GT's fitted [second pair] and run as recommended [36/42] pressures solo and [38/44] two up. Only see about 12,000kms. before replacing them. By the way, the original Pirelli's were removed with about 8,000kms. on them. In fact couldn't wait for them to wear out.  :821: :158:

    I got almost 13000 miles out of my first set of GT A spec and the front was done, but I could have run the rear another 1 or 2000. I didn't have any cupping or scalloping though. I run mine at 38/42psi. Waiting to see how this set does.

    I agree and the fact that a bike probably spends more time upright than leaning is bound to result in odd tyre wear.

    All ways have run 40 psi front 42 psi rear

    Me too  :028:

    Other people’s mileage may vary but on both my atiger and Trophy I believe anything less than 40 to be a little soft. Running 40they seem to be wearing well and no funny wear patterns.

    I'd like to know how you guys come up with a figure of 40psi for the front in the first place? I take it that that is a cold pressure so what does the TPMS display when the tyres are hot?

    I've always wondered how each manufacturer comes up with  a pressure in the first place, I'm assuming that they have far more time & money to trial/test so why think that you/I know any better??
