Another Tyre Question

Recommended Posts

Hi

Has anyboby fitted 235/70/15 tyres on their Rav in place of the 235/60/15 tyres that are fitted as standard as Ive been offered a set at a good price,but if they affect the car badly in any way I'll give them a miss

Thanks

Les

Cannae see a problem, Les, maybe in fact an improvement by virtue of tyre wall increasing in height...........helps ride the potholed roads we pay a fortune for. Wife's winter tyres change it from 55 to 65 and smoothes oot the bumps a wee bit.

As far as I'm aware the 70 profile tyre will have a larger diameter, and will slow the speedometer (ie the speedo will show a slightly lower speed) - which may not matter as the majority of speedos over-read. Bear in mind that it is illegal for the speedo to under-read - and show a speed lower than you're actually doing.

Ok, your speedo will misread by -7.1% and you will also lose quite a bit of acceleration.

At 30 mph you will be doing 32 and at 70 mph you will be doing 75.

Thanks for the speedy reply's,my concern is with it being an auto and any adverse effects as I'm a bit wary knowing the problems that the auto ravs of the same year as mine seem to have,and for just a tad more I can get a set of bridgestones where the others where two pirrelis and two goodyear,and I would prefer the same back and front....oh decisions decisions !!!

On both my Avensis the speedos have over read by ~7% on the standard tyres so if your RAV is the same this would put you yours pretty much spot on (if you are in the habit of allowing for that speedo difference you would have to remember that there no longer was one).

Your insurance company would probably also need to be informed & they may vary your premium.

Just read the last reply from GreyRacer and the last thing I want is to lose any acceleration as I've just come from a Honda civic 1.7 vtec coupe and I miss the performance as it is,looks like the its the Bridgestones then.....And thanks for the help,all sorted in the time it took to make a coffee and saved me maybe dropping a b****ck

Cheers

I would go for the peace of mind the Bridgestones offer. Any savings on the others would be wiped out by any problems should they arise.

Anywayhowz, Les........avoid Pirellis IMHO..........what a blessed racket they make at motorway speeds. Anything from 50mph upwards and you need heavy rock on the radio to offset. Bridgestones APPARENTLY slightly noisier than Yokohamas.
