Hi all, although i have just joined i am not new to this, but its great...however i am new to posting stuff....

I have a 95 Cinq S 899cc, which i have only owned for about a month, originally just buying it for an emergency car to get to work etc, but its true what they say, they do grow on you, so i am now thinking of keeping it and modding it.....BUT, i think i have just done a catastrophic error, i have just bought some 13 rims, but i dont think they are going to fit :mad:
can some1 please point me in the right direction...many thanks

Cheers guys, your knowledge and info is much appreciated.
what size tyres do you think would be best if i were to drop it 50mm/60mm. 175.50.13?

sorry to bother you guys again, but i'm having trouble sourcing tyres...what would be the highest profile i could go without having problems, (scrubbing etc) when dropping it 60mm.
I'm still using 13s (5.5j, ET 35) i found 155/65 R13 73T TW do you think these would be ok?

cheers guys (y)
 
You're probably looking at around 530mm natural diameter, or a little under 100mm of sidewall on a 13" rim or just over 85mm with 14" rims. That gives you 155/65R13 with a H (130mph) speed rating T (118mph) is a notch to low. Personally I'd go for 175/50R13 if you want to keep to 13x5.5j rims, read below if you want to know why.

At 14" 195/45R14 should fit but 185/50R14 however at 540mm will probably become very tight and hard to fit in the arches. I know this doesn't answer your question but I think it will apply to other people doing a search.

Why do you want high profile tyres?

For gear ratio reasons you'll gain virtually nothing in economy, as the engine is under low loads it'll rev freely with smaller throttle openings & thus less fuel. I know the difference between 175/50R13 and 175/50R15 was very little, if anything negative.

If it's for comfort oddly enough a wider slightly lower profile tyre will do you better as the wider tread will tend to soak up the smaller road imperfections better letting the suspension deal with larger imperfections in a more controlled manner. Something like a 205/35 will be to far and you'll have such stiff sidewalls that you'll lose what you gain but something like a 195/45 profile would be a nice compromise.

the lower profile (170/50/13 and 185/50/14) cost a fooking bomb!!! (less common). The higher profile is much much cheaper but they don't fit right so as suggested go for the 175/50/13 mate!

What I have found is: Cheap wheels means expensive tyres. Expensive wheels means cheaper tyres.

I got some 'free' 13" alloys but it was going to cost a 'fortune' to put 4 new tyres on at the right size. I then got some 5.5"x14" wheels and again the tyres were still expensive. I then spent a bit more on 6"x14" wheels (still quite cheap though) and then suddenly the tyres came in at about £40 each. So spending more on alloys can pay in the long run.

I have to say I really like 195/40R14 tyres, though they're not that cheap at £70 a corner. However the combination of 195 wide tyres around PGT brakes & a real -40mm ride height drop with -40mm springs is nice.
 
Of course, the other point is that performance 195/45/14s are way cheaper than everyday 13" tyres..............


Actually they are not that cheap having just replaced 2 and then there is the fun of having arguments with dicks that don't beleive the size exists and am i sure that I haven't got 16" wheels :tosser: worked out at £55 per corner all in for rainsport 2's although there may be cheeper makes

I got 205/45/16 T1-R's for the MX-5 for less
