OK to use same tyre sizes all round on a 2WD?

I've got 215/65's on standard Mazda 15inch alloys.

Any chance you could work out what profile 17's would bring it into line??

Complicated

- bl**dy weird I'd say.
Logically the 65 aspect tyres on 17" rims should pretty much correct your speedo. But, as BDC fitted tyres of virtually the same circumference as his originals and the speedo then read correct, I think I should go back to sleep before my brain hurts too much

Yes, you right MM...but it feels quicker though doesn't it?

I've just been using it to puzzle out what size I need on my new 16"s to drop revs about 250rpm at 60mph.

According to the calculator 225/60-16 will do and it looks like that is a very popular size as loads of makes/types are available from about £35.

I like the look of this one but wonder if they are any good for £35.50 each.

Goodride SW602 225/60 R16 98H
* Winter tyres
* M+S marking
* Speed Index H: These tyres are approved for speeds of up to up to 130 mph/210 km/h !

I'll get me coat. . . .

That's right and it's why by travelling on Concorde you could arrive in New York before you left London. If it had been 14,000mph even Concorde couldn't have done it, you'd have needed a Saturn 5 and some very brown trousers.

So my initial approximation was nearer the mark after all... Its all relative i suppose eh? ( I didn't research the figures by the way,i just pulled them from my head in jest)

Now then...Scanners tyres... I've not heard of the make goodride,is that another tyre manufacturer under another name?

£35 is very good for 16"s...How about a pic of the rims scanner?

Each to their own scanner but just googled goodride tyre review & they seem to have some pretty poor write-ups.

Could be fine for a Bongo though & certainly cheap.

At this time of year especially I worry about 2 tonne + vehicles on shitty "Made in the World" tyres

I just hope they aren't careering in my direction all locked up!
Maybe its years of 2 wheeled motoring but I just don't skimp on tyres - trees and concrete walls are pretty imoveable! - never mind the poor pedestrian who can't move out the way fast enough - just hope they haven't got a combo of crap tyres AND bullbars

Fender defender bars dandy!

They are an important safety issue, thats why i've fitted some to my bongo.

As the pedestrian is catapulted from the front of the bongo, if fender defenders are in place, the pedestrian can easily hold onto the f/d's till the bongo comes to a stop.

Without this essential safety aid, the airborn,careless walker would simply fly through the air,which may cause him an injury or two.

That is a different tyre, I was specifically looking at the winter ones in the picture. The local fitting centre is Huntingdon Performance Tyres which I normally use, I'll ask Mark there for his opinion.

Here are the rims.

As you can see I need to up the load index for the rears.

Oh, yes...TSW hockenheim's... a decent retro rim

trouble is you don't know what the shitty tyres are until you try them. I've paid ££££'s and got shitty tyres, as I think has someone in a recent post on here. I've also paid ££'s and got good tyres I couldn't fault. One set of Michelins I had were the worst I ever had, a set of cheap Firestones were some of the best. It can even vary within the same brand and tread pattern depending on where they are made. Some of the best Firestones were from Argentina and the worst Michelins from Stoke-on-Trent.
If they are crap they will get changed...............if they get bought in the first place that is.

Very nice set of wheels all the same.

Feeling a bit green already. . .

Fair n'uf scanner, you sound as though you what you want/talking about. I've still got vivid memories of when I first drove my Bongo back from Newcastle to Edinburgh on a set of recently fitted by the importer "Fate" Argentinian "skidmasters"...........don't think they used rubber - more like steer hide

. They were certainly capable of their name!

A set of GoodYears were soon fitted
