Mazda designed the chassis under the Fiat 124 for LIGHT weight wheels like we offer here. Mazda ND Gen Miata 17x7 wheels start at just 15 pounds for 17x7 BBS version, and top out at 17.2 pounds for standard 17x7 but Fiat went for style and stock Abarth wheels are ridiculously heavy at 22 pounds each for just 17x7. Thus, the good news is Fiat 124 owners have the opportunity with a change to lighter wheels to improve ride quality and make the Fiat 214 handle even better. Stock tire sizes are 195/50/16 on 16x6.5 and 205/45/17 on 17x7, which means the stock tire diameters range from 23.6 to 24.3 inch. Within that range there are interesting upgrade sizes to consider. TPMS operates off ABS system with the ND, that means NO sensors in the wheels to worry about for most Fiat 124 (though oddly the Abarth version alone has sensors in the wheels that will need to be transfered to new wheels or replaced).
195/50/16 tire size fits within the fenders on wheels down to about 35mm offset. For customers seeking more performance in 16 inch sizes consider 205/50/16 up through 225/45 on 16x7 and 16x8 wheels with higher offset. See product description for 16x8 Enkei RPF1 for pictures of this popular choice on our own Fiat 124.
With stock size 205/45/17 tires you can run offsets as low as 40mm and still fit in factory fenders with 1 degree negative camber or better, we have run 38mm with more camber. An easy upgrade in 17 inch is 215/45/17 and that fits with our wheel choices that are 42mm to 50mm offsets.
MAX TIRE SIZE that will fit in stock fenders without a fender roll is 235/40/17 using our Advanti Racing, Konig HyperGram, and 6UL Racing Wheels in either 17x8 or 17x9, as long as you have about 1.5 degrees of negative camber or more. If the car is lowered and/or raced, this size will typically rub the plastic fender liners inside the wheel well at full steering lock and/or over big bumps/dips in turns depending on amount of lowering and amount of lowering and amount of negative camber (same story with taller 225/45/17). This is all even more true for 245/40/17, which can be used by SCCA STR competitors with a fender roll. Picture here is our own Fiat 124 with our 17x8 Bronze 6UL wheels and 245/40 tires, and lowered with KONI SPORT shocks and our Race Spec Springs.
Please note that most 15 inch wheels do NOT clear the big brake calipers, even on cars without the Brembo upgrade, and the effective offset to make 15 inch clear the brakes will usually put the tire outside the fender lip (and the fender arch on ND is bigger than prior miatas, doesn't look right with 15 inch anyway). Thus, we do NOT suggest 15 inch choices on the Fiat 124.
Torque lugs to 85 ft/lbs and check that torque again every week for first month of owning new wheels or lugs.
Wheel Care. Most modern wheels are clear coated just like the paint on your car. Therefore, do NOT use anything on your wheels that you would not use on your Miata's paint. Only clear coat safe products should be used on wheels. We like to put a coat of fresh car wax on new wheels before we put them on our Miatas here, helps keep them clean.
