Help... with the steering on my f360

sanham · 05-09-2011, 12:52 PM

I just changed the tires (and wheels) from the original size to a 225/35/19 front and 289/35/19 rears, to my 03 Modena, and now i feel the car like it wants to change from one side to the other from the road, at high speed (around 105 mph and 145 mph) Can some one help me whit this? I think it has to be aligned again, but not sure, what do you recommend?

If you've just changed all 4 wheels and tyres first thing I'd be doing is ensuring tyre pressures are correct and getting 4 wheel alignment done.

Alignment, static and dynamic balancing of the wheels are important since you might start wearing your tires unevenly if alignment is off.

Try your car on a perfectly flat tarmac. Wider tires always do more tracing and tracking on uneven tarmac. My old Modena was even more magic on 225 front and 295 rear. It should be a very nice upgrade. Nevertheless, wider tires will always cause a little more eagerness on uneven and lorry tracked roads.

Good luck and congratulations to a good upgrade.

Beware a little extra in the wet and when breaking into a corner. The Modena in general does not like breaking too far into the corner - spin warning!

Thanks to both. air pressure is OK, and with the other set of tires was ok, so I think Ill have to align it may be it will get better...

Here is a picture, I think is awesome (obviously is one of my babies......)

what brand is the tires, and does each state "outer side" on the outside of each?

I have seen tires incorrectly mounted that can cause the problem you mentioned.

Gcalo..... the tires are well mounted, are Potenzas, and by the way they´re great...... I ALLREADY SOLVED THE PROBLEM..... it was a steering adjustment required in one tire was the camber little open......

yesterday I took it to the race trak and was a very nice track dey (like most of track days)

I would take that car to another shop and get a 4 wheel alignment.
