tires near the end_safe?

I searched so pardon if some of this has been covered but I didn't see a definitive answer so thought i'd post.

About to do a 500 mile round trip this weekend, mainly straights (from DC to Va Beach, VA).

My oem hi sports have 4600 miles on them (just got the bike a month ago with about 4000). Riding thus far has been fine, nothing screaming to me out of ordinary.

Doing spot checks and looks like most of my wear is in middle of tire, wear bars on 'sides' are not even close to showing.

The wear bars smack in the middle have a tiny tiny bit of tread before they are flush with the rest of tire. When I say tiny i'd say about the width of maybe 2 pieces of paper. The rear tire is also sort of flat in the middle probably from mainly straight riding.

I plan to replace these in the next week or but the question is, do you think it's safe for this road trip or should I scramble and replace them before the trip?

I'll try to post pics tomorrow.

if you can handle it you should definitely replace the tire, but if you don't replace it just keep and eye on it and be cautious.

Peace of mind is worth it.

You don't want threads showing and then have to worry about ripping along at superslab speeds risking a potential blowout.

Good grief I only got 3500 out of mine!

Throw them away ya tight arse

After replacing them with Pilot Road 2's (yum on a big stick here) I cut the worn rear in half to see exactly how much was left of the tyre. I replaced at the wear indicators. Results.

Exterior rubber (pre cord) – 1.2mm
Cords (steel belts etc) – 1.0mm
Internal rubber (inside of tyre) – 2.0mm

The absolute total left in the centre of this tyre was 4.2 mm

On top of that the Hi Sports are an old tech tyre and you can make big improvements to your Hornet with a change. I bet the front still has plenty of legal tread but it is cupped on the sides. If you have got that mileage out of them I suggest you get a new pair of dual compound sport touring tyre and you'll be a happy chap.

yeah, one night of sleep and another look at the tires- no brainer, ordering new tires, to be installed Friday AM before my trip. Only catch now is rain is in the forecast so all may change anyhow, but hey safety is my number 1 concern so i'll deal with it.

Got a good deal on Dunlop Qualifers and gettn em on Friday morning at RnR cycles in Sterling VA, really cool shop for anyone in the area.

When they are at the wear bars in the center there's not much life left. I would NOT take that 500 mile trip on those tires.

Iceman is right on track when he said they go fast at the end.

I replaced my Michelins with Metzelers before the Michelins hit 500 miles. I don't trust those wear indicators.;-)

Rule of thumb - If you have any doubts at all, better to err on the saide of safety ! Replace them !

We cut up an old race tire and there's like a 1/2' of rubber under the wear bars on bridgestones.

We run em till the sides look like slicks, but we're Broke Ass.

If your gonna replace the tire anyway, do it before the trip for peace of mind.

tires paid for and can't wait to get em on now...

anything special i need to do as far as scuffing them?

i've heard anything from just get up and ride, take it easy, to using dawn dish soap,to going in a lot and doing a few figure 8s and u-turns...


i'll probably do a combination of everything, but if anyone has any other suggestions may as well take em!

just relax for the first 20 miles, especially if it's wet out

take some turns at a very relaxed pace but lean it over a little

you'll be fine

dish wash/dawn ??? not necessary

New tyres - my theory in getting rid of any slippery mould release agents off new tyres is heat - go for a decent ride to warm them up properly - easy on the corners etc. I've never had any issues.
I back up my theory with this: - chicken strips - often with new tyres it is some time until you get it right over to a tyres edge, maybe a few rides after fitting them - if heat does not dissipate the slippery stuff then the first time you were over that edge you'd be on your arse, however this is not the case if the tyres have been properly warm up several times.
