So, what difference does it make by changing the front profile from 60 to either 65 or 70?

quikcer steering in a nutshell

Cheers Dickie, sorry to labour the point, but...

Assuming that the profile affects the cross sectional (is that a real word?) appearance, does a higher profile make the tyre more pointed then?

Have had the 748 for about 6 weeks and haven't really felt that it was particularly quick on the steering, especially from side to side.

Dickieducati, I think youve got a bit mixed up with how changing profiles affects the bike if you go from a 60 to a 65 or 70 profile tyre of the same make/type it will in actuall fact slow the turn in down, because in effect you are raising the front ride height

[dickieducati]

cant argue with that, i thought raising the profile would speed up turn in full stop. didnt think about ride height being an issue. just goes to show how much i know..................... fcuk all!

at least someone on here knows what they're talking about.

i'll get my coat.

apologies

I've done 5 track days on my Diablo Corsas, and I must say: They are really great. The confidence in the front (from stock 60 to 70-profile) is mega (to use a foreign word). No more tucking sensations.

Also, while most of the others tyres looked ready for the bin, mine has just a bit of orange texture.

However, I would recommend keeping a fairly low pressure on the track, more or less regardless of track temperature 31psi front and 29psi rear was optimal for me.

Well, they are so great I've just gotten some Rennsports Well I only ride track days anyway so why not go as close to slicks as I can...

Please accept apologies, I did try and research before asking the question and would really appreciate some clarity on the front profile sizes.

I currenlty have super corsa's which support a 70 front and before I read this thread probaly would of happily stuck with it but... is there any real benefit on 60 or 65?

No intended track or wet use.

Thanks in advance and seasons greetings to all.

I've had my 748s for three months, and will probably be switching the front to a 70 profile when I next change. I agree that the steering isn't that quick side to side, but that tucking/tipping in sensation was a surprise initially whcih everyone says is due to the 60 section...
