Tolga ULGUR Posted September 29, 2021 Share Posted September 29, 2021 Hello, I have to clarify one point for my next P-40N project I am not quite sure about the wheel size of this P-40N "Geronimo". Normally P-40Ns have smaller tires than the previous version but some of them replaced by bigger early type wheels in the field. It seems that Geronimo has earlier big wheels. What do you think about this? Thanks in advance Link to comment Share on other sites More sharing options...
thierry laurent Posted September 29, 2021 Share Posted September 29, 2021 Indeed it looks like you are right but the weight of the guys on the wing may also result in a more compressed oleo and give the feeling the wheel diameter is larger than it is.

bdthoresen Posted October 12, 2021 Share Posted October 12, 2021 Tolga- It would appear that the early batches of P-40N’s came equipped with the standard 30” P-40 wheel. They were later produced with the lighter weight 27” 8-spoked wheel in an effort to reduce weight. They also produced some with two fifty calibers removed from the wings, for a total of four. Most units in the field reinstalled them. So, it is entirely possible “Geronimo” was an early N model with the 30” wheels. You photo seems to prove this out….. Looking forward to seeing what you do with her……. Thor MikeMaben and Tolga ULGUR 1 1 Link to comment Share on other sites More sharing options...

waroff Posted October 15, 2021 Share Posted October 15, 2021 Geronimo is 42-105112, P40N-5. the wheels are 27" diameter, they appear bigger because the oleo strut are compressed. The P40 N, 42-104829 and subsequent receive a new landing gear fitted with 27" wheel. The old and new landing gear are not interchangeable, so the wheel cannot to be 30" Anthony in NZ 1 Link to comment Share on other sites More sharing options...

A friend who is heavily involved in P-40 Rebuilds also mentioned they often use T-6 wheels as they are also correct for an 'N'. But again I have not looked into this yet to confirm.

But I still think there were some N's fitted with 30". The following N's wheel looks like larger. And there is only a man on wingroot And another one , Zotz decal instruction mentions that White 21 fitted with larger wheels. MikeMaben 1 Link to comment Share on other sites More sharing options...
