Could use some advice with respect to tires and rims on my 1990 Plus 8 that I acquired a few months ago. Have a front end vibration so took the car in to have wheels dynamically balanced. Shop examined car said there were two issues needed addressing first.

1) wheels (stock Morgan) are not hub-centric and I need spacers to fix and make hub centric . Anyone know what spacer size is needed and where to acquire them? I don't even know what they are called. Rim size below.

2) tires are seven yrs old and told they need replaced (not worn-just old) . I imagine this question will result in some diverse opinions but what is best replacement tire for normal road use (no track use)? Currently running Uniroyal Rain Tyre 205/60 R15 91v. Came with car. Spare (older) is Uniroyal Rally 340/60. Rims are Morgan 15x6.5. 307 inset. Code #8mks.

ALL help appreciated. Thanks. John.
