Race tyres - wet intermediate?

[flymo]

Hi,

Anybody got any recommendations for wet inter tyres to fit the SV?

I understand that Pirelli only do the full on wet tyre in 160 rears.

[sv650k4]

aye a set of done full wet tyres lol.;)

[Alpinestarhero]

Flymo, some wheels like bandit wheels can fit onto the SV...i think a few people have fitted a bandit 1200 wheel on their road bikes, which might allow the use of 180-section rears; can you get 180-section inters?

aye u could get 180 inters easy enough im sure as thats the size of tyres the 600ss take etc...so they will be easy enough got!;)

[Alpinestarhero]

Another idea I had is trying to find a good soft road tyre, and maybe getting a bit more tread cut into it - some road tyres have the edges slick, but they are a soft compound...get the tread cut to the edge, and you have a god intermediate tyre?

aye thats another thing that could be done easy enough tho i dont have a clue wot it would work like thats the thing but ther would be no harm in trying it.

Well slick tyres get cut sometimes, I've seen that been done on the TV...I guess, for my idea, the tread pattern of the road tyre can just be extended as it is to the edge.

Or, in the damp, do a sean emmet and fit a wet front, and slick rear. Should average out :bball:

yip people get ther slicks cut.

Not in mintwins you cant.

Your best bet should you be able to get hold of a 3rd set of wheels is to run a set of sha*ged wets as you inters

But remember have a control tyre means you can only run wets if the race is declared wet so if not you are stuck with road legal

[tranx]

For minitwins I would have thought that the Pirelli Super Corsa's would handle a bit of damp fine? After all they arn't full slicks!

However a softer road biased compound that warms up quicker would probably do better in those inbetween wet/dry stages. However what if any benefit you'd see I don't know.

[flymo]

Ok, thanks for the ideas. It seems clear that there isnt a proper inter in use for our size wheels. I dont want to go using alternate sizes and as mentioned, cant be used under minitwins regs anyway.

I totally destroyed a set of Bridgestone wets last year in 5 laps of Anglesey as I was caught out with the weather conditions. It started raining as we assembled in the holding area and I thought "Yes! sorted." then the sun came out 5 minutes later and I was sliding around the track like I was on a GP bike :-) great feeling but crap lap times.

Also, I felt sorry for the poor guy who was fighting behind me as he was getting showered in rubber from my shredded rear.

My thinking behind this was that I've probably used full wets twice, maybe three times in two years. Inters on the other hand would be perfect for damp track that isnt quite wet enough. I think I'll see how we go with SuperCorsa Pros and full Pirelli wets to start with, maybe consider dropping the wets for a good sticky road tyre with a good tread pattern.

[Blue_SV650S]

Supercorsas are actually pretty good in the wet, but lean over too much and you are on the slick part ? you WILL go down ;)

I suggest getting some 208s (amazingly good in the wet) or a proper race tyre that simply has groves all the way to the edge 8)

Although you will destroy them quickly (what does that matter in poxy 7 lap races ;)), if you want the pace, using old proper wets in the damp is the best solution mind ;)

Forget true 'intermediates' as even if you could find them in your size, they are illegal ;)

Don't AVON do a road legal inter? :scratch:

Dont mind destroying them at all, the problem I had was that I was sliding all over the show and couldnt accelerate out of the bends anywhere near as hard as the guys I was battling with. was fun but slow.

I didnt realise they were illegal in the class, I thought 'Wet tyre' meant anything other than slick your honour :confused:, honest.

yes thats what i was gona say my self if its an inbetween condition the dry tyres will work ok as you probley wont be running full slicks.

As Blue points out though, when you get leaned over the Pirellis go slick and you'll end up on your backside. Ok up to a point but if the track is too damp I cant see these being competetive. I think a good sticky road tyre with plenty of grooves would be better for damp conditions.

Its pretty rare in my experience that its truly wet enough for full rain tyres. Sometimes yes, but mostly not.

Decisions decisions.

They are Dunlop race tyres yes. I think they are superseded now? But were good in all conditions from bone dry to full wet!! 8)

In a 7 lap sprint, unless you have really screwed up and it is bone dry (like in your example), not just a damp day, you won’t seriously overheat wets, especially if you keep in the wetter stuff on the straights if a dry line has formed.

On a day like you suggested you would mind, so some 208s would have been a safer bet as they work well across the full range!! 8)

[flymo]

Sorted. £73 for a rear too, thats cheap!

Certainly worth a punt somewhere through the season. Think I'll buy a set of these and keep 'em in the van for a race weekend.

They might be a bit old now mind ;)

Try them in the dry too, they give great feedback 8)

Not as ultimately grippy as later rubber, but VERY user friendly :riding:

yes but you not have where it gose slick cut down 2 the side?then that would give a bit more.


but anyways your sorted now arnt ya??what did you end up getting or what?;)

I don't actually know for sure, but 'modifying' the tyres is bound to be illegal too under minitwin regs ;)

Yep, treads must be moulded not cut.

[sv650k4]

a ry thats that answered then lol! i wasnt 2 sure but i no thers people who cut tyres etc...so thought maby you could do it but if you say its no allowed then thats it.

[sv650k4]

will the wirral 100 be running all the minitwin regs or what?

[flymo]

Yes we will, the regs are not exactly the same but they are very close.

[sv650k4]

a ryt i was just wondering.;)

If a race is declared wet you have free choice to use whatever you want. so either road tyres, supercorsa's, full wets or any combination of the three.

Any other time road legal unmodified only.

Avon do road legal wets that off the top of my head are called avon pro extreme(or something similar) but are primarily designed for supermoto's. They probably wont apreciated an extra 50kg's of bike but in theory you are allowed to use them in dry conditions within the bemsee rules.

[Olly]

The Avon proXtremes are bloody horrible on an SV. I tried some last year in the wet at Snetterton, and hated them.

I tend to use Pilot Road 2s in damp conditions :)

[flymo]

Right, had my first weekend of the season so can report back.

The Saturday practice at Anglesey was cold and wet. I expected it might be this way and had the bike pre-loaded with a set of Dunlop 208RR's (cheers Blue).

Started off on a damp track, new tyres, new bike, new brakes and every bolt I'ld fitted over the past three months playing on my mind. But........in a word, superb! The 208RR's were a perfect tyre for these conditions. Once I got used to the bike my lap times came tumbling down and I was getting faster causing a few slides on the very damp sections. Nothing too major though.

The next day it wasnt so wet, the track was partly damp and in some sections beginning to dry due to the very high wind speed. Again, the 208's were perfect.

So, left them on the bike all weekend and got myself a 2nd place finish in the championship points race. top day!

And , to throw a spanner in the works.......no tyre warmers! :-) I'll go find that other thread to continue that saga!

[Blue_SV650S]

If it was damp/drying, sounds like you made the right move with the 208s!! 8)

As I said, they work well wet or dry and in the middle .. obviously there are better tyres these days for full dry or full wet, but in changing conditions, 208s are a godsend as they work 'well/ok' in all!! ;)

Yep. they were excellent. The bike had a handling problem though that for now I'm guessing was downt to the rear shock (remember that GSXR1000 shock I was fretting over?)

Hopefully the Ohlins will arive for my next round and I'll be able to compare like for like then. But these tyres are cheap too in comparison to Pirelli's so unless its full dry and I have a chance to get some heat into them I'll favour the 208s.

[billy061]

Yes, tranx is right but if you're stuck, the Pirelli wets are good in the dry but wear out quick, as I found out at Brands after those pesky sidecars delayed the start of a race long enough for it to dry out, doh!!
