Fitting 8x13 wheels

Postby Milts » Fri Jan 15, 2016 12:20 am

Hello

I have a minor fitted with adjustable front coilovers, adjustable rose jointed lower arms, JLH ford disc brake setup, escort rear axle.

I have bought some 8x13 minilight style wheels, could or should a Tyre alignment specialist be able to acheive a workable setup for me? The car is for road use only.

I have only trial fitted the front wheel, and clearance between wheel rim and trunnion seems fairly tight see photo...hopefully!
Perhaps a 7" rim with a spacer is another option? (The cars weight is being supported on scissor jack with the original wheel being approx 1" off the ground)

Any recommendations or thoughts welcome, thanks in advance. Steve.

The wheel is not going to move any closer, but I would have thought the tyres in the correct size range for those wheels would probably get close to the suspension, and be quite heavy on the steering on the road.

If you spaced them out further to get more clearance the steering would probably get even heavier.

Also the further out you go the more stress on the wheel studs and stub axle.

If you had gone the other way up to 15" diameter (rather than down to a 13") because the kingpin is sloping away from the wheel you can get a wider tyre on and because you are probably then using a lower profile it will not be bulging on the sidewall as much either.

If you are going to use it a lot I would have thought 5.5 or 6 was a lot more suitable width but you are right to consult a tyre specialist or JLH if you have his hubs.

Realistically, the widest tyre (and minimum size for this rim) you can get easily for an 8 x 13 is a 205/60. This may foul the upright depending on make of tyre, but if it does just use solid spacers to move the wheel slightly out. Use the minimum thickness you can get away with - trial it (for fit only - don't use on the road) with washers to miss the upright, then measure the washers and get a spacer of this thickness.
You will obviously hit the wing with this wheel/tyre combo, so I assume you have extended the wheelarches to suit.

Thanks for the replies guys, i have fitted my new set of wheels and generally happy with the result and look.
I decided to fit 195/60 x 13 tyres all round

My original intentions were to fit flared arches or widened wings all round, however the 8" rear wheels only slightly protrude from the wing and to be honest i am happy with that look, but i will need to tweak the wing lip for extra clearance or remove the lowering blocks :( The fronts amazingly have good clearance.

Now the front wheels will need extended arches if i stick with them.

So my dilemma now is

1. Do i down size for 7" fronts and replicate the 'look' from those on the rear, keep the front wings as is and just tweak the wing lip as necessary.

2. Or add spacers to the rear wheels bringing them out even further (probably not ideal) to match the look on the front then add wider arches all round!

I'll try to add some photos from yesterday, unfortunately the battery died on the camera and i wasn't able to include a front and rear view. will try and add those later tho.

Having charged the battery in my camera i can now include those other photos showing the current wheel offsets.

Following on from my earlier question 'Are Tyre Specialists are able to determine a good alignment set-up?' It appears alignment is only set and adjusted against the car manufacturers data, and is not able to determine an 'ideal set-up' purely alone. Which is what i was trying to ask, at least that is how i understand it.

So for now the jury is still out :?

There are a lot of things that affect a good set up.

A tyre specialist that is involved in motorsport may have a better idea. A normal so called "specialist" may not understand enough and as you say simply set it by the book.

For the normal tracking alignment; in general with a rear wheel drive car they are toe in as they spread nearer parallel as the car is pushed forward from the rear.

Bearing in mind the book settings are for both narrow tyres and standard bushes, with wider tyres and polybushes you can get it set parallel or close and monitor tyre wear. But never toe out as that will make the front end very skittish and unpredictable.

7's on the front won't make a huge difference. Realistically a 6 is what you need if you want to miss the wheelarch. I also think you'll hit the rears on hard cornering. Depending on how good you are at body work, you can turn the wheelarch lips outwards and upwards to both cover the tyres and give clearance. I've seen it done both very well (looks factory) and also poorly (looks a bodge), but any decent body shop should find it a breeze.
Car looks good though.

Thanks for tips and ideas given, I have been offered a 7" wheel to trial fit on the front so will see how that looks.

I have watched some YouTube clips of youngsters flaring the arches on their cars with heat guns and various types of flaring 'tools' with some success, something to ponder with!

Anyway with a Wing and a Flare we will get there! Cheers.

Ratrodmog on this site does a fine set of fiberglass dtm style flared arches.....give him a shout.
I have a pair on the back of my ratrod(search for "Pat the Rat")

Yes, the VW crowd can essentially bend the inner lip inwards and gently force the wing out slightly, but we are talking paper thin metal here. On a Minor what you have to do is bend the lip to the outside which will normally involve pie cutting the edge of the wing and moving in sections. When you have bent it to give you the desired clearance/appearance, it can be dollied into shape and the 'pie cuts' either welded/brazed/fibreglassed to finish. Of course, this will involve some remedial paintwork, but the finished job both back and front is lovely. If you want a 'lip' on the wing edge I've used thick welding rod or even conduit to form an edge.
