Okay, I know this is a repost from another thread, but the original threads title is not specific enough for this topic. So I decided I'd create this thread with a proper title.



Okay... here's a little list of tire sizes & required offsets for the P11 & P10. This list has been compiled based on knowledge I have gained from buying, selling, testing, & just talking about wheels on the G20. If I have not tested it myself, then I have talked to someone who has...otherwise, the parameters are based on calculations derived from tested & known fitments.

Please review & let me know if there are any other known combos that I may have missed.

P11 tire fitments:

*195/60/15 - 24.2" diameter (35-45mm offset required)*(99-01 Touring)
*195/65/15 - 25" diameter(35-45mm offset required)*(99-02 Standard)
205/50/15 - 23.1" diameter (35-45mm offset required)
205/55/15 - 23.9" diameter (38-45mm offset required)

205/45/16 - 23.3" diameter (35-45mm offset required)
*205/50/16 - 24.1" diameter (35-45mm offset required)*('02 Sport)
215/40/16 - 22.9" diameter (32-45mm offset required)
215/45/16 - 23.6" diameter (38-45mm offset required)
225/40/16 - 23.1" diameter (35-45mm offset required)
225/45/16 - 24" diameter (42-45mm offset required)
225/50/16 - on stock 16 inch sport wheels (according to Marty)

205/40/17 - 23.5" diameter (35-45mm offset required)-reinforced sidewall recommended
205/45/17 - 24.3" diameter (38-45mm offset required)
205/50/17 - 25.1" diameter (38-45mm offset required)
215/40/17 - 23.8" diameter (38-45mm offset required)
215/45/17 - 24.7" diameter (40-45mm offset required)
225/40/17 - 24.1" diameter (42-45mm offset required)
225/45/17 - 25.1" diameter (42-45mm offset required)

215/35/18 - 23.9" diameter (38-45mm offset required)-reinforced sidewall recommended
215/40/18 - 24.8" diameter (40-45mm offset required)
225/35/18 - 24.2" diameter (42-45mm offset required)
225/40/18 - 25.1" diameter (42-45mm offset required)

215/35/19 - 24.9" diameter (42-45mm offset required)
225/35/19 - 25.2" diameter (42-45mm offset required)

*stock setup

Note on P11 offsets- All offsets listed assuming the car is not lowered more than 3"... otherwise, fender lip trimming may be required... also, in most cases, a 2-6mm spacer may be used on the rear just for the purpose of making the width of the rear track visually match that of the front(not neccesarily a performance gain).

P10 tire fitments:

185/60/14 - 22.7" diameter (35-45mm offset required)
185/65/14 - 23.5" diameter (35-45mm offset required)
195/55/14 - 22.4" diameter (38-45mm offset required)
*195/60/14 - 23.2" diameter (35-45mm offset required)*(91-93 P10)
*195/65/14 - 24" diameter (35-45mm offset required)*(93.5-96 P10)
205/60/14 - 23.7" diameter (38-42mm offset required)

195/50/15 - 22.7" diameter (35-45mm offset required)
195/55/15 - 23.4" diameter (35-42mm offset required)
195/60/15 - 24.2" diameter (35-38mm offset required)
205/50/15 - 23.1" diameter (38-42mm offset required)
205/55/15 - 23.9" diameter (38mm offset required)

195/50/16 - 23.7" diameter (35-42mm offset required)
205/40/16 - 22.5" diameter (38-45mm offset required)
205/45/16 - 23.3" diameter (38-42mm offset required)
205/50/16 - 24.1" diameter (38-40mm offset required)
215/40/16 - 22.8" diameter (40-42mm offset required)
215/45/16 - 23.6" diameter (40mm offset required w/ 7.5" rims...40-42mm w/ 7" rims) correction

205/40/17 - 23.5" diameter (38-40mm offset required)
205/45/17 - 24.3" diameter (38mm offset required)
215/40/17 - 23.8" diameter (40mm offset required w/ 7.5" rims...40-42mm w/ 7" rims)
215/35/18 - 23.9" diameter (40mm offset required w/ 7.5" rims...40-42mm w/ 7" rims)

*stock setup

Note on P10 offsets & sizes available- All offsets listed assuming the car is not lowered more than 3"... otherwise, fender lip trimming may be required... some other sizes & alternate offsets are known to fit a P10 with the use of spacers, and/or trimming the fender lips.

Example of sizes known to fit P10 w/ clearance modifications:

225/40/16(40mm offset)
215/35/19(40mm offset)

Wheel width ranges that will work with all tires listed above:

14x6-14x7
15x6-15x7
16x6.5-16x7.5
17x7-17x8
18x7-18x8
19x7-19x8
