"4. Tire Tread: XML Global Part Number (CAI): 110510 Description: 395/85 R20 XML TL 161G Rim Diameter: 20 inches (50.8 cm) Comments: Principally used on Stryker Infantry Carrier Vehicle" As per: http://www.faqs.org/rulings/rulings2003NYJ81184.html You've got a metric size there, so converting it to inches will give you (on the full size thing anyway): -20 inch rim -46.4 inches overall diameter -15.6 inch width. Hopes that helps! Either way, glad to hear I'm not the only Loony-Toon here! Maybe we'll have to swap ideas. > Date: Tue, 24 Nov 2009 09:38:19 -0800 > Subject: [TANKS] Re: Complete Newbie... > From: [email protected] > To: [email protected] > > Hi James, I have been wanting to build a stryker for a while, so don't > think your all alone in wanting to build a wheeled vehicle. > So tell me guys, does anyone know what the scale size of a stryker > tire would be?
