Purchased them less than a year ago but did not end up using them so they are still in good condition. There are four tyres for the price of 65.00 If you have any further questions please contact me with the details provided. Collection Only! I am selling a set of 4 18 inch league alloys without tyres, and can offer to deliver or pick up. Delivery charge of 40. Brand: League Model: 190 Size: 18 Inch Bolt Pattern: Most 4 & 5 Stud patterns, 4x100, 4x108, 5x110, 5x114 Offset: 30 to 40 Colour: Polished, Black Style: Twin 10 Spoke, Polished Face, Polished Lip, Deep Dish 8 hole multi stud, so fit most 4 or 5 stud fitments. Alloys were used for around a year so have general wear and tear and minor scruffs. Alloys have corrosion on the chrome as have been lying in my garage for around 1 year, as can be seen within the pictures. The corrosion on the chrome is not noticeable from far away but is clear to see from quite close up, but this can be easily resolved by refurbushing if required. Alloys cost 600 brand new, low asking price reflects the condition so grab urself a bargain anyone know of someone who tints windows cheap??? only doing the rear van doors on a seat inca/caddy preferably in south aberdeenshire or north t
