Any problem replacing standard fit 185/55/15 with 185/65/15?
The ride on the standard tyres is 'crashy'........and the 65 profile tyres are significantly cheaper. :)
Any advice, chaps.
-
Only the possible insurance implications really... Is it one of the option sizes?

Not sure if a '65' profile tyre is listed as an option.
I'm guessing it will raise the gearing slightly. Hopefully the ride would be improved.

Obviously there would be a slight under-read on the speedo too :y

Shouldn't be a problem if I sling a set of 65 profile tyres on.

If it's a size quoted in the manual for wheels of the same dimensions (diameter x rim width) then happy days... :y

Al.....I don't have the handbook to hand.
The 65 profile tyre has a larger overall diameter so I wonder if it may rub.

There is a lot of leeway for tyre and wheel widths, so I wouldn't worry about that. For instance, going back a few years, the tyre manufacturers suggested that a 205/60x13 tyre would fit a wheel between 5.5" and 8.5"! Not that it works very well at either end of that range.
If the 65 profile tyre is a standard Corsa size then they'll be fine. It's hardly a massive difference anyway.

The middle number is a percentage of the width (first number). So 55% of 185 is 101.75 and 65% is 120.25, that's quite a difference.

And why wheel width has a bearing..

There isn't a standard as to how you measure that 185mm(or whatever) so the actual width varies across different tyre brands.

Yep.....I was amazed to find that a 235/45/17 Goodyear Eagle F1 was about an inch wider than the crappy 235/45/17 Michelin Primacy it replaced.

That clears things up nicely. ;D

Happy with Dunlop Blueresponse... similar size, 195/65/15 V88, done about 1,100 miles and grip well in wet, dry,damp and frosty conditions, and reasonably priced :y

These look like a good replacement for 185/55/15.
£50.99 fitted at Kwik Fit. 'A' rated for wet weather performance and also quiet at 68 Db. :y

The chavs at the Corsa C forum say 195/50/15 can be used as a direct replacement for standard fit 185/55/15.
This means I'd save about £15-£20 a corner. Overall diameter is within 1% and the extra 10mm of width shouldn't present a problem.
So...which to choose, Dunlop Blue Response or Goodyear Efficient Grip Performance?
Both £50.99 including fitting.

My money would be on Goodyear :y
-
As Dunlop and Goodyear are the same company there can't be much between them? :-\
-

Mine is on the Dunlops... Efficient grip are crap when things get slippery IMHO...
-
I am biased against Dunlop as I have seen that many deformed SP4's we used to call them banana tyres ;D ;D
For another thirty bob a tyre I would have Conti Premium Contact 5. :y
