Super singles on front

[newmercman]

Harry Monk:
I’ve got them on the steer axle of mine, were there when I bought it, but I’ve been told they have an adverse effect on fuel consumption, any thoughts?

They can have a negative effect on fuel consumption, but that all depends on what they’re replacing, if you had a set of tyres with really poor rolling resistance then super singles with good rolling resistance may improve things. A trailer tyre will usually have lower rolling resistance than a steer tyre or drive tyre and anyway, the steer axle rolling resistance has the least effect on fuel consumption, so for once I would look at tyres on their lifespan

The only drawback with super singles on the front is that it totally [zb]s up the ride

385/55/22.5?

the standard super single tyre is 385/65/22.5

Low height unit.

not necessarily, most 55s I’ve seen lately have been on normal height trucks with air suspension on steer axle.

Mine is a low height unit that i want to put them on

What makes you say that?
I’d have to say the opposite

I would have thought a s/s inflated just right would give a more cushioned ride

Your truck will fail the mot unless you get the plate changed to say that your running supers on the front!

Never had an mot failure yet. My present truck has been thru 6 tests with out a mention.

after driving thet same truck with super singles and standard 295/80’s on the front, i must admit, i prefer the handling of the 295/80’s

i find that the steering is not as good especially on wet/slippery surfaces if super singles are fitted

you can go up in tyre size without a plate change but you have to change the plate to come down in size.i have just dropped an 8 wheeler on to 295"S from 315"s on the back axle"s it cost £28 for a newplate

Helps if they have some tread on!

That’s my lesson for the day!

Tbh that makes a mockery of the plating system IMO. I’m sure I’ll lose no sleep over it though.

Experience

I had an FH that ran on 295/80s then put a set of 385/65s on it and it was like driving on solid tyres, did the same on a 144 Scania but the other way around and the ride improved dramatically

you might have a point there

I had a chat with the Michelin rep today, he was saying come Euro6 the front axle weight will be too heavy for 295/80’s on the front, we will all be using 315/70’s

It will be a long time before i,m worrying about what tyres are on a euro 6 truck

Same as that, it’s reckoned euro 6 will put £10,000 onto the cost of a new tractor unit so I can’t see them flying out of the dealers’ doors.

[cold_up_north]

Seen my 2nd euro 6 truck today, and funnily enough it was on 315/70 all round

I really cant see how?, a V8 scania is aprox 250kg heavier than a straight six and most of that weight must be on the front and they dont all have super singles on?.

We’ve got a couple of 13 reg 460 XL Volvo FHs, we (unfortunatly) buy bog standard motors, these 2 XLs are running on 70 rather than 80, so that must be the new standard for Volvo.

[cold_up_north]

70’s have a lower rolling resistance, so they are fitting them for better fuel, the daf ate is the same.
