[evouk]

Can someone help here im a bit confused.

What size tyres do i need to go on 15 inch speedlines on my cup car.

are they 195 50 15

195 55 15

or 185 ........

HELP?

195 50 15 most people use. originally 185 55 15,s as fitted by renault on the road motors not sure about the cups though

i have just spent about 65mins doing a complete search of the club regarding tyres and the respective sizes and brands! lol :lol:

My car (which i pick up tomorrow) is running 195/45/15 toyo proxes t1-s. they look superb and from my research it appears they offer a great compromise between road holding grip, sidewall stiffness, as well as general wear and tear. the cheaper option is definately the 195/50/15's as they simply have more applications so are made in greater numbers. As you state, the standard fitment is 185/55/15 but as these have a limited application they are more 'specilised' and as with anything in life that carries that title you end up paying a premium for it. I havent driven my williams yet so i cant make an informed decision, i have merely made my own mind up after reading as many posts as i could!

185/55/15's - expensive, standard size from new,

195/50/15's - cheaper, wider rubber for extra grip but weigh more

195/45/15's - more expensive than 50's, smaller sidewall ratio so stiffer
sidewall and better 'sideways' traction :D

I'd gor for 45's on a track car.

:lol:

[Martin]

185/55/15's - expensive, better ride, best for bumpy uneven backroad blasts

195/50/15's - cheaper, no noticeable increase in grip over 185s, less sidewall flex compared to 185/55

195/45/15's - poor over harsh surfaces, better turn in due to stiffer sidewall....pricier than 50 profile

I go for 195/50s everytime....best compromise between b road/ a road and cost

[drsmith1979]

like he said lol

why dont you go for some slicks? Im sure Martin has some laying around! got to be better than any road tyre?!

[evouk]

cheers dudes,

i have slicks and semi slicks but need some for the wet weather as my dunlop race wets are no good

[evouk]

i see just got some online quotes and the toyo t1r come in at 49 each for what ever profile you go for!!

[drsmith1979]

have a check out on mytyres.co.uk

195/50/15's =£31.10 each

195/45/15's =£43.30 each

[Jamie.]

ive got 185/55's on mine but i have had a go in 195/50's which i preferred and will swap to when i need a new tyre as the price for 185/55 is stupid.

[evouk]

thanks just ordered some 195 50 15 toyo t1 r's for 124 delivered..........

45 profile were 178 delivered

[Dancliovalver]

thats where i got my 195/50/R15 proxis T1-Rs from!!!

http://www.mytyres.co.uk/start.html

when i bought them, it was £130 delivered for 4, went down to quikfit on a sunday when they do cash in hand jobs and got em fitted for £15 for the lot :lol:

[evouk]

lol :D

In my experience,

I originally used to use 185/55/15 but then i fancied a change to 195/45/15.

Both were toyo proxes.

185/55/15 - Far smoother ride than the latter.

195/45/15 - Would not consider having anything else having swapped to these. If your after comfort then these aren't the way forward, you feel every bump in the road, and i mean every bump,

but...the handling is without question a lot sharper than 195/55/15 in my opinion, and the grip and road holding is immense, id go as far to say as the difference between CHALK & CHEESE.

:D

[dan 16v]

As above really, i had 195/45's on my old car and yes u feel everything on the road but yes cornering did feel sharper to me. Im currently running 195/50's on my turbines as these in yokos from blackcircles are a total bargin. like £120 for 4.

[James_R]

195/45's for looks, 50's for perf.

For track use I run A539's no need running slicks unless you're racing/competing IMO, or at least can't justify £400 on tyres for a trackday.

I've had 539's on all season and they're still halfworn.

Toyo's just over heat and rip to bits as do F1's admittly while they're ok temps wise they offer better grip but once cooked (2-3laps) 539's are still going.

Not to mention 539's are cheaper, gutted they stopped making them, I'm buying them up now.

For wet, I'd run rainsports definately better wet grip than anything else I've used.

[dan 16v]

Stop making 539's!!! Arg!! Whats the replacement?

[Swervin_Mervin]

PCC had 45s on when I got it. Fvcking wank is the only way to describe it.

Was absoultely tons better when I put the track 195/50s on.

[MAXIBOY]

were they the same tyre except for size

[Swervin_Mervin]

All A539 yes. Truly horrendous. First thought was how shockingly out teh tracking must be.

Not had that done yet but as soon as I just put 50s on it virtually wiped out all the issues.

Now it's on 55s. :twisted:

[evouk]

cheers all,

toyos arrived friday afternoon and fitted ready for oulton......... shame it got cancelled :)

[richy]

lol i use 195/50/15 for my road tyres on the valver(eagle F1 gsd3) and have full slicks in 15" size, cant remember profile tho

my williams is on 185/55/15 eagle F1s

I work in the tyre game and a539's are no where near as good as toyos, i rest my case that theyre cheaper. Im not saying that they are a bad tyre, not at all, because they aren't, but toyos are better.

[Matty86]

i've gone for 195 45 because i think they look better :P

you guys are making me reconsider though

I didn't have my 195 50s on for long enough to notice really :(
