14x6 How big can the tyres b?
Timothy King
I've got 14x6 inch five spokes and was going to use them on a 5.0l
Capri. The original tires were 205/70/14. Is there a limit to the
width of the tire I can put on these rims?
ie: could I put 215/60/R14's on it? 225/14's do such tires exist?
Thanks

I have 15x6 inch rims, and 205/60 is a little large for my rims.
195/60 is a much better fit, and 195/50 may fit as well but I've
never tried. 195/60's are also much easier to find in 14" than
in 15".

First generation Camaros and Firebirds came with 14x6 rims and what amounts to
205/70R14 tires today. For handling, you want the widest rim that can
accomodate a tire. This minimizes sidewall bulge which allows the tire to
contribute to side movement, or roll, in a curve. You can put 235s on a 14
inch rim, but it wouldn't be a good idea - 205 or 215 is about the max.
Changing the tread surface by 10 milimeters isn't very much as there are 25.4
milimeters to the inch. If you change by 30 militmeters, that is a bit over
half and inch on either side of the rim, and will begin to show improvements
in traction at this point.
At the rear, switching to 15x7s with the appropriate backspacing, should
allow the rear fenderwells to accomodate 245/50 or 245/60s. The choice
will be which tire diameter you want. Both result in a tread increase of 1.6
inches over the 205s. But the 245/50s are .65 inches shorter, while the
245/60s are 1.3 inches taller.
I'd go with the 245/50s because they are closer in diameter to your
current tires, and will give you the mechanical advantage of installing a
slightly lower (higher numerically) final drive ratio. Plus, any error in
your speedometer will report that you are driving a tad faster than you are
really driving.
Up front, 225/50s should do fine with the stock offset. I know that some
Mustangs have 245s up front, but that my require a fender flare. But, you
have nothing to lose by trying. The problem up front is usually inner fender
well contact during steering. If there is room on the outside, the common
solution is to reduce wheel's tire mounting pad offset by an inch so the
tire moves away from the suspension and towards the street. This may not be
the case with your car, but let's assume that it is and I can suggest how to
measure for a negative backspace change. You can use the same general method
to measure the effects of positive backspace (increasing the mounting pad
offset moving the tires away from the street and towards the suspension).
Remember that negative offset pushes the tire away from the inner wheel
housing and that positive offest tucks tires closer to the inner wheel housing.
To check the effect of a one inch negative offset, run a straightedge
(prefereably a level) vertically pressed against the rim and note where it
contacts the fender well. Then move the straigtedge away from the tire by one
inch and note where it makes contact. This is your new starting point ( as
if you had installed the 205s with one inch of negative offset ). Now move the
level another 0.8 inches away from the tire and see where it meets the
outer wheel housing.
You already KNOW that the inner wheel housing and suspension isn't going to be
a problem because you will have moved it 0.2 net inches away from the inner
wheel well and suspension (-1.0 + 0.8 = -0.2). You want to determine if the
effect of pushing the tire towards the outer wheel housing by 1.8 inches is OK
(1.0 + 0.8 = 1.8). Also remember that the 245/50 tire is half an inch shorter
than your current 205/70 tires.
If it appears that the offset wheel/tire combination will clear OK, then
measure the offset of your stock tire. You can ask or you can measure. If
you measure, and I would, remove a wheel from the car and lay it so the inner
(brake) side of the tire is facing up. Release some air so that you can lay a
straightedge across the rim. Then measure the distance from the straightedge
to the mounting pad. That's your stock offset (eg 4 inches). If you want a
wheel with 1 inch of negative offset, your new wheel should have a 3 inch
offset.
Note that some wheels come in a series of 1/2 offsets. But try the 1 inch
check for 245/50r15s up front first. With some luck, maybe you can have
245/50s at all four corners. :-)

And don't forget: to wide of a tire can be rubbing against suspension

I think the Fiero stock alloys are 6.5 inch. I'm certain
215/60's fit on a 6 inch rim in any case though.

I think 215/60 is a good bit shorter than 205/70. Dont let
that stop you though :-)

Its a bit of an annoyance that 215/60/14's arent made in many
of the performance tire types. s-rated bfgs' and goodyear HR4's
are about it..
