Tuffant 18" Steel Wheels

[veebs]

Hi all,

So these fancy new tuffant steel wheels seem to be filtering out into the market - has anyone got any feedback on them?

I read somewhere that previous attempts at steel wheels on these cars ended up confusing the TR system into unusual results - not sure how much reality there is behind that, or how it was even tested to prove the wheel was at fault, and not the ballast holding the steering wheel

Plenty of people run steel wheels with spacers in the US without issues to the traction control system.

Anyway I’ve got a set of Tuffants on with mud tyres in 265/60 and have been driving around town mostly with only one dirt excursion so far. Traction control was required on some loose gravelly sand and everything worked normally. Here is a list of actual weights that are from my wheels.

19" LR rim with HT Goodyears - 32kg
18" Compo rim with KO2 265/60 [~50% worn] - 36kg
18" Tuffant rim with Monsta 265/60 [new] - 41kg

Note that the rim weight difference is ~5kg. Tuffant weighs 18kg but I haven’t weighed a bare Compo or LR rim. All measured via home scale.

How would steel wheels confuse the TR system?

It wouldn’t...

Likely written by the same Muppet that lives on the AULRO FB page... the “mechanic of 25 years” who tried to tell everyone that “EGTs do a clean out when headlights are on...” 🤪. Seriously!!!!

When pointed out that Was wrong he changed it to EGRs...

Don't get all hussy - I read it here, in reference to it being the reason why Gordon never developed a steel wheel (and indeed as one driver for him sticking with alloy based rims).

Sounds like Scott recalls a similar discussion, as it was the weight of the wheels people were suspecting to cause the issue.

Point is, people have them, and they are working well, yes?

I mention real weights because some people are interested in the comparison for unsprung weight. I can’t comment on whether the extra mass is significant or not in that respect. I’ve not seen anything substantive re traction control and wheel weight.

Even if that theory proved to be somewhat correct, all that would be happening is that the TR would not be optimal. Everything is a trade off. Alloy is not optimal for strength, repair and cost.
Would you likely notice the difference in the TR working at 98% instead of 100% - probably not. For a couple of thousand dollars, are you willing to gain 2%?

Full disclosure: i now have Compomotives and TuffAnts. My mud tyres are on the tuffants, AT's on the compomotives.

Not Hussy at all...

Just laughing.... any increase in mass (tyres will do that also) will provide more inertia for the TR to have to deal with.

Gordon did develop a steel 18 inch wheel and I have a couple for spares on my D4. I now have an extra Conti and a D3 18 inch rim for the rear (after modifying my early model type rear brakes to fit the D3 alloy). His were very heavy and he may not have sold them widely but he did get some made.

Just on the TR issue of performance.
This is also why it is critical to fit high quality pads and rotors...
