225/70 or 225/75 R15?

[Cunning Plan]

I currently have 225/70/15 tyres on my Cherokee XJ at the moment, but they all need changing, so I was thinking of going up to 225/75/15 to gain the extra 11mm for a few reasons:

It should reduce the gearing and engine RPM at cruising speeds, potentially meaning a saving in fuel.

They fill the arches more, which looks better.

The cost difference is hardly noticeable.

I realise the speedo may read slighly under the actual speed, however as I know a tolerance is built in for the speedos to over-read, it should be fine.

Apart from that, is there any reason I should stay with the 225/70s?

Hell'uva side wall!

Nothing to add really. I'm about to change my wheels as I'm sick of the 215/65 side wall movement I get.

No, there isn't.

Great! I'll start gathering quotes

Just ordered mine from Black Circles. As I have a garage over the way that'll fit them for £10 a wheel, balanced etc, I ring them up and ask for their best price for just delivered.

4 x Kuhmos 245 / 50 R16 = £325 with next day delivery.

Shall hopefully get them fitted for Saturdays trip to the Pod!

That's not bad. The cheapest I can find is £10 + £2.50 for disposal, each tyre. meaning another £10 on-top

I got my last ones for £9, fitted, balanced, valves and disposal, each.

Disposal at your local recycling centre should be free for domestic users.

It is?

I'll look into this if it saves £10!

We're allowed 5 tyres a year at my local tip!
