[Say When!]

Hi Slot Racer Online Forum Members:

Merry Christmas!

I am a new member and a novice seeking TIRE Tips advice.

I have late 1990s and early 2000s vintage Ninco 1/32 analog Porsche 911 SC & 934 slot cars with “50” prefix part numbers featuring flared rear wheel arches, ribbed tires, and prominent "whale tail" or "tea tray" spoilers made in Spain running on an analog Ninco track, specifically:

Ninco 50331 Porsche 934 #9 black window 

Ninco 50334 Porsche 934 #58 black window

Ninco 50371 Porsche 911 SC #4 black window

Ninco 50386 Porsche 911 SC #1 black window

Ninco 50573 Porsche 911 SC #16 black window

Ninco 50652 Porsche 911 SC #18 clear window with driver Gulf livery San Remo Rally

Please attached pictures.

My internet research (please see “Data Sources” below) suggests that the stock tire sizes for the late 1990s and early 2000s vintage Ninco 1/32 analog Porsche 911 SC & 934 slot cars are:

Front Tires: 19mm (diameter) x 10mm (width)
Rear Tires: 20mm (diameter) x 11mm (width)

However, that is subject to verification!

My track is a Ninco analog 1/32 track used by BEGINNER slot car racers.
Mostly my grandchildren (age 10 and under).

Question:

Can any Slot Racer Online Forum Members:

1.    Validate the correct FRONT & REAR tire sizes for my specific Ninco Porsches?
2.    For cars running on a NINCO analog track by BEGINNERS:
3.    Reply with Tips for Front & Rear tires upgrade recommendations (including Brand, Part# & Hyperlinks)?

If “Yes", please enter data below and send it to me:

FRONT Tire Size: ?mm (diameter) x ?mm (width)
Recommended FRONT Tire Upgrade including:
Brand: ?
Part#: ?
Hyperlink: ?

REAR Tire Size: ?mm (diameter) x ?mm (width)

Thank you in advance for any Tips you can offer!

I welcome any insights and/or advice that you may have to offer.

Finally, I am seeking to purchase a User License for "Ultimate Racer 3” track design software.

Thanks again!

Kind regards,
“Say When!”
