Split rims
Turbo Mini Forums

Ok am looking at getting my 1100 special wheels turned into split rims, Im looking to go 7" wide but would there be a beneifit going 8" wide? would love the look but Im after more of a weekend and track toy.
So would be going 8" wide trash the handling?

You won't get any decent tyres that will fit an 8" rim though..

Yeah that's another problem. will ao32s not stretch over?

Whats the point in stretching them? Theres no extra tread on the road, saying that im on 7" wide.

Im sure i read somewhere that the recommended wheel width for optimum performance on the A032r tyre is 5.5.

Like i said they look the bollox i think.
Do you have some pics of your 7" wide wheels?

Look good on slicks, yeah ill dig one out for you

Matt W

the maxium width for a 165/70/10 A032 tyre is 6 inch wide

I was looking at 13x7 or 12x 6 what would u recommend

I seriously doubt it!

why are they unsafe?

My build thread..

Because theyre stretched. 165mm tyre divided by 25.5mm = 6.49". So that is the maximum rim you should fit them to. People get away with 7" but 8" is too much.

Ideally as said above 165 tyres should be fitted to a 5.5" rim

I seriously doubt it!

do people with 10x7's find the handling is not great then?

i ask as i have 10x7" wheels waiting to go on mine once its built!

There's absolutely nothing wrong with stretched tyres

NOT

:o thats a lot of stretch!!

Dunlop
"RIM WIDTH
Correct rim width ensures flex at the designed flex point in a tire sidewall for optimum tire performance.
If the rim is too wide, the flex point moves towards the rim area, causing heat buildup in the lower sidewall, which reduces tire life and could result in failure. Either too narrow or too wide of a rim can result in uneven tread/pavement contact pressure causing uneven wear and potentially reduced traction, or increased vulnerability to bead dis-lodgement. "

Toyo
"Serious personal injury or death can result from failure to select the proper tire and rim: Tire MUST match the width and diameter requirements of the rim. When mounting truck type radial tires use only wheels approved for radial tires.

NEVER put flammable substances in tire/rim assemblies at any time. Never put any flammable substance into a tire/rim assembly and attempt to ignite to seat the beads.

NOTE TO PROFESSIONAL TIRE INSTALLERS: Exceeding the maximum bead seating pressure — The tire service person must NEVER INFLATE BEYOND 40 POUNDS PRESSURE TO SEAT BEADS unless specified by the tire manufacturer! "

Some more info from Yokohama.

"CUSTOMIZING
RIM/WHEEL WIDTH
Each Yokohama tire has a specific rim width range on which the tire can be mounted. Failure to follow rim width recommendations may result in poor tire performance or possible wheel and/or tire failure.

Below is a quick reference chart listing each Yokohama tire size and the acceptable rim widths for that size. Choosing a wheel near the middle of the range will give a balance between ride quality and handling. A wider wheel will improve handling at the expense of ride quality, while a narrower wheel will improve ride quality at the expense of handling. Consider these compromises when selecting wheels."

From the same web forum a police officer made this comment

We would have to rely on expert advice as to the propensity of such modifications to add risk. Individual and even multiple experiences where no actual risk has occurred are not, in themselves, reasons for saying that no risk exists.

If I was using such a vehicle, I'd be concerned
A) That it wouldn't be insured.
B) That if I was stopped I'd likely be considered for the various offences I've mentioned, and
C) If I was to cause a serious collision through loss of control, I'd be concerned that the expert evidence gained in relation to the effect of use of tyres way outside manufacturers guidelines could easily alter the charge from Sec 3 Careless - fine and points, to Sec 2 dangerous (dangerous state of vehicle) - 12months minimum ban, up to 2 years imprisonment, to Sec 1 death by dangerous - up to 14 years imprisonment.

What do your insurers say about such tyre stretching? Do they know about it? What do you do for MOTs? Do you take the wheels off, then refit them afterwards? Is the tyre wear uniform? Do you have to have significantly higher tyre pressures? Have you checked the tyres for heat after a longish drive?

I have no real issues with modifications if there is no safety compromise. I can't see that there is no added risk with such a tyre stretch. I'd be forced therefore (using the FM test) to report for summons, and seek expert advice, and also check the matter through the insurers.


Reaing though just that topic I learned that the police use a rule of thumb based on first impressions. The FM rule. The Fuck Me! rule. A rule that if your first instinct is to think "Fuck Me!" there is likely something wrong with it. I would tend to agree with this train of thought.

FM rule. I like it.

Coincidently, I got my mini special wheels split to 6" because its going to be a road car. A friend of mine has his split to 7" but he'll be running slicks on the strip

out of interest, what width do the migs run their wets on?

I think theyre limited to a 6.5" rim, Jim will know better though

I seriously doubt it!

all the Mig wet sets i have refurbed are 6.5" wide , the narrower wheel opens up the tread , a wider wheel will close the tread up,
