175s ?

cauchoiskev · Post by **cauchoiskev** » Thu Jan 25, 2007 7:36 pm

I'm thinking about changing the rubbish tyres on the estate (sportiva). Locally, Uniroyals are at 30% off, so about 30 quid a tyre.

Now, normally I think that Citroen know what they are doing, so I fit the recommended size (165/70). However, 175/65 is actually a bit cheaper ! So, I'm tempted. Any opinions ?

If the CT don't have a problem with it, go ahead. Uniroyals are good tyres and at 60% of the cost of Michelins, they are probably a good deal.

I`ve had 175-70-14s, 175-65-14s and 165-70-14s on my BXs and never found any noticeable difference between them.

175/65 14 was a standard fitting on 19TZS/TZi Bxs on the same size rim, so you should have no worries about them, Just make sure fit them in axle pairs. Its not wise to have wider tyres on the front though!

My DTR Turbo Estate has always had 175/65 x 14's on it. The original roadtest commented that 165's were too small for the car. Incidentally the mighty ZX 1.9D has the 175/65 x 14's as standard.

speaking of tyres for a BX: I recently put 175 70 14 Bridgestone tyres on my TZi wagon and they are much better than the previous tyres which I put on (new) which were Michelin Energy 175 70 14s I got nearly 50,000 kms out of them.

Much better ride with the Bridgestones, it seems to me and handling seems as good? Believe it or not!

Hope this is readable from the photo, but this is the tyre specifications stuck to the door pillar of my BX TZi wagon

Would the speedo be calibrated to take account of this, I wonder?

Some well known British car manufacturers used to enhance their products performance by deliberately using incorrectly calibrated speedometers. The UK requirement is that the thing is within 10% (either way), some European countries stipulate that it mustn't (overread?) - if you search on the internet you will see that there were a number of committees on this subject alone when the last group of countries joined the EEC. (The process is called 'harmonisation.')

Odometers are generally more accurate -I think 3% is usual. They simply count cable revolutions on a BX.

That tyre pressure sticker is interesting - as a different one is used in UK. Ours is on the drivers side door pillar and has red car symbols - and I think mentions the tyre size. This was to my knowledge used through 89 to 94.

Epilogue to the 175 question : if you've got a French-registered car, don't do it.

I was wary enough to go to the local Controle Technique (MOT) place, and they said the car would fail with 175s.

Why's that then?

Do they have a massive list of what each car was fitted with from factory?

Well, more or less. They have a database with the manufacturer's approved tyres for each model. 175s on a 19 diesel = fail.
